Dear Customers, Economic activity all around the world is currently being shaped by two main factors: the ongoing Covid-19 pandemic and a much more positive element that offers us hope for the future—sustainability and the associated environmental and climate conservation. to vehicle manufacturing, building construction and the packaging industry—we can now offer you, our customers, safer alternatives in many areas of everyday use, all at the same high standards of quality you are used to. Like many other enterprises, here at Jowat we are constantly re-examining our portfolio and the decisions we make, asking ourselves: How can we make our adhesives, our pro- cesses and the resulting products even ligh- ter, give them a longer service life, and reduce the amount of resources they use? You will find some of the answers to this question in this issue of the Jowat Magazine. Read on to find out about the environmentally friendly and health-promoting ‘green adhesives’ we are manufacturing for a number of different applications. From the furniture industry »Our objective: reliable adhesive solutions that don’t rely on fossil raw materials.« We also want to take this opportunity to present our progress so far in researching sustainable resources for the manufacture of adhesives. Jowat SE’s objective is to develop reliable adhesive solutions that no longer rely solely on fossil raw materials when it comes to production. We hope this magazine will be a source of inspiration as we report on the opportu- nities for making your adhesive processes more responsible and sustainable in the future—with help from Jowat SE.

GREEN ADHESIVES Bonding Goes Green For Jowat, sustainability is more than just a trend. While many companies are just starting out on their journey towards becoming environmentally friendly, by this point the adhesive experts have been treading the green path for many years. With the diverse ‘Jowat Green Adhesives’ range, which focuses on adhesives themselves as well as on the bonding process, Jowat is already fulfilling the sustainability requirements for a wide range of industries, therefore establishing a bond with future generations and helping to ensure that they can enjoy a liveable world. One of the key elements in Jowat’s sustainable adhesives portfolio is the company’s use of renewable raw materials. 4
How can we make the future of bonding more responsible? This is a question Jowat began to tackle some time ago—long before sustain- ability targets became a hot political and social topic. The globally active adhesive manufac- turer has been paying close attention to high quality standards and environmental and user friendliness in its products for many years, so it is well-placed to handle the increasing demand for sustainable applications. “More and more of our customers are now asking about sustainable adhesive solutions,” reports Andreas Weymann, team leader in Product Management at Jowat. “And with that in mind, we already have a proven and diverse range of ‘green’ adhesives to offer them.” The term ‘Jowat Green Adhesives’ refers to a portfolio of adhesives that has been carefully compiled according to defined sustainability criteria. Green Solutions for a Wide Range of Industries The sustainable formulations of Jowat's adhesives are being used in a wide range of applications. “We have now reached a point where we can provide a ‘green’ alternative to conventional adhesives for every industry we cater to,” Weymann continues. In the auto- motive industry, for example, the enterprise's low-VOC adhesives and formulations with a low content of volatile organic compounds ensure a healthy air quality and a comfort- able driving experience for those inside the vehicle, all while maintaining high standards of process safety in production. And when it comes to food packaging, Jowat supplies MOSH/MOAH-free bonding solutions that comply with the strict standards required under food safety laws. In the construction and furniture production industries, Jowat reserves special attention for its woodworking adhesives. Compared with concrete, wood is a renewable materi- al that has minimal negative impact on the environment—providing forests that require protection as specialized ecosystems are left unharmed—and helps to create a healthy at- mosphere in rooms. With this in mind, the adhesives specialist has come up with a wide range of product solutions for load-bearing timber components that are compatible with the natural characteristics of wood. 5
GREEN ADHESIVES Renewable raw materials are not the only important consideration when it comes to sustainability—consumer safety is also a top priority. So What Can Green Adhesives Do? Green adhesives promise a lot—but do they deliver on that promise? Thanks to the pos- itive market feedback, the answer is clear: »We provide our customers with access to sustainable applications that don’t put them at a disadvan- tage elsewhere.« Andreas Weymann, Product Management Team Leader yes, they do! “Our customers have been espe- cially impressed by the fact that there is no dip in our established high standards of quality. We are providing them with access to sustain- able applications that don’t put them at a dis- advantage elsewhere,” Andreas Weymann is keen to stress. Sustainability is diverse—and so are Jowat’s Green Adhesives, helping as they do to improve sustainability in many diffe- rent ways. For instance, the use of bio-based raw materials in Jowatherm® GROW prod- ucts saves resources and thereby provides a future-oriented alternative to substances such as petroleum. Sustainable adhesive solutions can also help to improve the safety of processors and cus- tomers by either cutting back on emissions and plasticizers or using adhesives that are not subject to hazard-labeling. At the same time, low-temperature hot-melt adhesives can be used at lower temperatures than their conven- tional counterparts, which significantly reduc- es energy consumption. All in all, Jowat’s green adhesives therefore represent an investment in environmental and climate conservation, which will continue to increase in importance as we look towards the future. Progress and Solidarity Jowat’s focus is on a sustainability strategy for the long term—not just with regard to the composition and use of its products, but also in terms of establishing lasting working relationships with its customers in order to develop new solutions. After all, our word is our bond. Our portfolio of green adhesives is already extremely diverse, and we plan to keep expanding it so that, together, Jowat and our partners can help to make both our present and our future more sustainable. 6
Sustainability is Diverse More responsible and environmentally conscious bonding—this is one of the key goals in Jowat SE’s mission statement. But just how do you go about making the bonding process more sustainable? With its “Green Adhesives,” Jowat has created a diverse range of adhesives that are more sustainable in terms of both the products themselves and the bonding applications for which they are used. Sustainability encompasses much more than simply nature conservation and try- ing to protect the environment. Employee and customer safety also plays a key role. In short: sustainability is diverse. And the same applies to Jowat’s sustainable adhe- sives. Jowat Green Adhesives help to improve sustainability in many different ways—for the natural world, for your company and for your home. In September 2021, Jowat presented its Green Adhesives at FACHPACK in Nuremberg, Germany. Renewable Raw Materials With its GROW series, Jowat is helping to cut back on resource consumption and conserve the en- vironment. These bio-based adhe- sives are manufactured primarily from renewable raw materials, such as plant oils. Despite this, they are just as clean and efficient to use as conventional bonding solutions. Healthy Living Adhesives that are low in harmful substances present minimal risk to users and end customers: Their lower levels of formaldehyde, plas- ticizers and other ingredients are welcomed by consumers, as is the minimal level of emissions pro- duced during processing. Occupational Health and Safety In accordance with the principle of substitution, reduced-mono- mer hot melt adhesives have a lower monomer isocyanate con- tent, which helps to improve occupational health and safety. Monomer-reduced adhesives are not subject to hazard labeling and do not require specialist training to process. (see page 13). Resource-saving Continued use of fossil raw mate- rials is one of the major environ- mental concerns of our times— resource-saving solutions are re- quired. Jowat supplies solutions, which reduce adhesive consump- tion and can be processed at low application temperatures, to sup- port a sustainable and cost-effi- cient production.

JOWAT – FACTS, FIGURES AND DATES SUSTAINABILITY AT JOWAT Assessing and reviewing your own sustainability efforts at regular intervals is part and parcel of being an environmentally conscious manufacturer. Jowat SE has published its Sustainability Report for the 2020 business year, defined key topics and set itself targets for resource conservation, green energy sources, and much more. The Sustainability Report is based on the United Nations’ 17 global Sustainable Development Goals (see Jowat Magazine 2021). 8 120young people have completed their apprenticeships at our Detmold site since 2000. 90% of them are still at Jowat today.Adhesive production10,00020,00030,00040,00050,00060,00070,00080,00090,000100,000Tonnes 2017 2020 87,000 of disinfectant were manufactured by Jowat for schools, hospitals, ﬁre stations and ambulance services in 2020.5,000 l

JOWAT SYMPOSIUM Digital Jowat Symposium: A Successful Debut Digital over local—a trend that has established itself in every industry and area of our lives due to the Covid-19 pandemic. And just like everyone else, Jowat SE’s events have also been affected. In light of this development, the Detmold-based adhesive experts launched an experiment in the summer of 2021: Rather than inviting visitors to its House of Technology as usual, Jowat hosted the 18th Jowat Symposium online. For the first time, Jowat SE took its symposium digital. The event was used to present new concepts and projects under the theme of sustain- ability. 10 10

In “Greenwashing—The Dark Side of Sus- tainability,” Jan-Peter Bölcke shone a light on the pitfalls of sustainability communica- tion and offered valuable tips on how to spot greenwashing—sustainability efforts that have been faked for image purposes. Markus Luersen from Jowat’s Application Techno- logy department and Christoph Funke of Re- search and Development used their talk to tackle another hot topic in the current cli- mate: “Ambient Air Analysis 2021—Know- ledge Beats Belief.” The series of seminars was rounded off on 22 June with “Bio-based or What? Fact-Check- ing Sustainability” by Dr Christian Schmidt from Jowat Research and De- velopment and the accompany- ing keynote speech by Dr. Vera Haye, managing director of the German Adhesives Association (IVK). Feedback to Be Proud Of All in all, Jowat SE is very pleased with how the series of online seminars turned out. “Par- ticipant numbers remained at an almost con- stant level across the four weeks,” says Verena Rüter of Jowat SE’s Marketing department in summary. “Of course, the whole thing was a learning curve for us as well. We will put the experience we have gained into other projects of this kind in the future.” User feedback on the event was also generally very positive, with special praise reserved for the easy-to-understand way in which the is- sues were explained and the interesting and varied approaches to the presentation—a result we can all be proud of! “In light of the positive responses, we would definitely con- sider repeating the project,” added Mrs. Rüter, offering a look to the future. For full length videos of the talks, visit: www.jowat.com/symposium By this point, the Jowat SE staff can usually organize the company’s symposium blind- folded—but 2021 introduced a completely new element, as the expert talks were given as digital exclusives for the first time. Just like everywhere else in the world, the plan- ning for this event was inevitably shaped by the Covid-19 pandemic. Originally sched- uled as an in-person event for autumn 2020, the symposium was initially brought forward to the summer before ultimately being trans- formed into a series of online seminars. In partnership with the Association of the German Furniture Industry and the Asso- ciations of the North Rhine-Westphalia Furniture Industry, Jowat decided to play it safe, even though the number of new Covid-19 infections was on the decline. As a result, se- lected speakers and their talks found their way onto the Internet over the course of four days in June 2021, starting with ‘Natural Jowat Hot Melt Adhesives—The Search for the Green Carbon Atom’ by Dr. Felix Starck of Jowat Research and Development. With 45 participants, this first talk got the event off to a successful start on 1 June. »We will put the experience we have gained into other pro- jects of this kind in the future.« Verena Rüter, Marketing A Consistently High Level One week later, Assistant to the Executive Board Timm Schulze provided an introduction to the world of monomer-reduced adhesives (see page 13), accompanied by Dr. Vanessa Decker from Research and Development, 1111
MR PUR EDGEBANDING At the Cutting Edge of the Furniture Industry Edgebanding is one of the most popular applications for Jowat adhesives. At the same time, however, it is a field that comes with plenty of challenges and specialist re- quirements. Jowat now offers a full range of non-hazardous edgebanding adhesives. Jowat subjects all of its edgebanding adhesives to rigorous testing before market launch. Edgebanding might not be a particularly well-known process in the wider world, but in the furniture industry—and so for Jowat— it is of huge importance. After all, an edge- band with a clean joint is a mark of quality for high-end furniture. In order to achieve this result, the adhesive used for the process needs to meet high standards. Quick crosslinking and high ini- tial strength are essential to both maintaining an efficient tempo throughout the processes and en- suring the bond is reliable. When bonding free-form edges or working on end products that will eventually be used in kitchens or bathrooms, there are also other special charac- teristics that are required to ensure optimum results. Improving Occupational Health and Safety With the Jowatherm-Reaktant® MR 607.90, Jowat has succeeded in developing an all-rounder that can handle a wide range of edgebanding applications and is also a reactive hot melt adhesive which is not subject to hazard labelling requirements. Since the adhesive’s monomeric isocyanate (diisocyanate) content is less than 0.1 percent, no specialized training is required to required 12 The new Jowatherm- Reaktant® MR 607.90 is part of Jowat’s Green Ad- hesives range (see page 4). for processing it—unlike conventional isocya- nate adhesives. By switching to monomer-re- duced adhesives, businesses can reduce their organisation workload while also helping to improve health and safety in the workplace. The latest additions to the portfolio are the premium variant Jowatherm-Reaktant® MR 608.90 for extremely delicate bondlines and the Jowatherm-Reaktant® MR 606.90 for free- form workpieces. New Beneﬁts, Proven Performance But it isn’t just the lack of specialist train- ing requirements that makes the MR PUR range for edgebanding impressive—these monomer-reduced bonding solutions can also match conventional products in terms of their application and performance. Due to their high degree of chemical and me- chanical resistance, they ensure edgeband- ing is made to last. As such, there is no need to be sceptical about making the switch. Jowat will be happy to advise and assist you throughout the changeover process in order to ensure that you can maintain the high- quality results you are used to with monomer- reduced adhesives.
NON-HAZARDOUS ADHESIVES SCHOOL’S OUT FOR THE MR CLASS ISO C Y A N ATES M ER MO N O What has changed since the restriction on diisocyanates came into effect in the summer of 2020 (see Jowat Magazine 2021)? Timm Schulze, assistant to the managing director for sales and marketing, provides insight into the current adaptation processes and the next steps. What has changed with regard to the restriction on monomer isocyanates? Timm Schulze: The first stage of the REACH regulation on approval restrictions for diiso- cyanates came into effect on 24 February. As a result, products with a diisocyanate content of more than 0.1 percent by weight must be labelled with the notice “As from 24 August 2023 adequate training is required before industrial or professional use.” The isocy- anate producers’ associations ISOPA (Eu- ropean Diisocyanate and Polyol Producers Association) and ALIPA (European Aliphat- ic Isocyanates Producer Association) have designed these training courses in partner- ship with the trade associations—in our case, FEICA (Association of the European Ad- hesive & Sealant Industry). The first training courses went online in English on 1 Novem- ber 2021, with the German versions follow- ing a month later. The training modules are highly complex and must be selected based on exposure. This means that more extensive training is required to use a hot melt adhe- sive than other substances, such as assembly foam. How can Jowat help with this? TS: The easiest way is for people to use Jowatherm-Reaktant® MR adhesives. “MR” stands for "monomer-reduced" and indicates a diisocyanate content of less than 0.1 percent by weight. This means that these adhesives do not bear a hazardous substances label, and can continue to be used without specialized training. Our portfolio of MR adhesives is con- stantly expanding, and we can now provide a monomer-reduced alternative in many fields of application for which we supply PUR hot melt adhesives. How have customers responded to the upcoming changes? TS: At the latest when they read the label, customers who purchase a product with the hazard symbol will be made aware of the training requirement. We have already reg- istered a significant increase in the demand for MR adhesives, but many of our customers are still unsure how to proceed. We continue to recommend looking into the issue as early as possible—this will help both us and our customers to avoid potential delays in the changeover process. Timm Schulze advises customers to make the switch to MR adhesives early. Don’t forget! Training for adhesives that contain monomers becomes a legal require- ment in August 2023. 13
PREPOLYMER ADHESIVES Solutions Made in Australia One-component, polyurethane-based prepolymer adhesives are true all-rounders: Apart from providing high performance and a wide range of adhesion, they also open the door to countless new applications due to their ability to bond many different substrates. At Jowat Australia, they play a very special role in our day-to-day work. Jowat SE’s Australian location in Ingleburn, just south of Sydney, now specializes in a range of these versatile, high-performance bonding solutions. Up until 2019, Jowat Aus- tralia mainly offered hot melt and dispersion adhesives. Then, the decision was made to focus on a new type of product. The change came just in time, as Managing Director Shane Devereaux explains: “At the end of March 2020, Australia closed its borders and initiated a lockdown due to the Covid-19 pan- demic. In spite of these difficult circumstanc- es, our technical account manager, Arne Haas, Australia usually conjures up images of koalas and Sydney— but at Jowat, it makes us think of single- component prepolymer adhesives. 14 worked untiringly with his colleagues, Rod Vella and Andrew Waud, to install, commission and improve our polyurethane prepolymer manufacturing facilities. As a result of this, we were able to put them into operation six months later.” Jowat Australia’s main market segment is timber construction, which has been huge- ly popular in Australia and New Zealand for many years. The benefits of load-bearing glu- lam construction in terms of environmental compatibility, safety and healthy living were recognized at an early stage. With impressive new wood-based buildings springing up everywhere, the industry has made a name for itself far beyond Australia’s borders, leading to more investment in the timber construction sector. In-House Production Until changes were made in the law in 2010, Jowat Australia specialized in offering phe- nolic resorcin-formaldehyde-based products. When the sale of PUR prepolymers was ap- proved, this opened up a whole new world of opportunity for Jowat in the Australian market. As a result, the company started to import the proven and successful Jowapur® range from Swiss manufacturing location in Buchrain. However, the long freight jour- neys halfway around the world were a cause for concern, and a solution was required. “By commissioning our own in-house pro- duction plant, we have managed to overcome this issue and put ourselves in a position to cater to the Australian market more efficiently. Our locally manufactured products give us a unique selling point on the Australian mar- ket,” says Shane Devereaux. Jowat now sells these adhesives both in Australia and beyond, also catering to the New Zealand, Indonesian and Vietnamese markets. The 1C prepolymer adhesives are used for laminating and finger- jointing glued laminated timber, as well as in the production of plywood. Tailored to the Needs of the Market Since 2020, Jowat Australia has been manu- facturing the main product range Jowapur® 681.xx and the thixotropics Jowapur® 677.xx and 676.xx in its own in-house production facility. With exclusive formulations such as Jowapur® 680.02 and 680.03, Jowat supplies bonding solutions for the jointing of 4-milli- meter micro fingerjoints. What is thixotropy? i The term thixotropy refers to a change in flow properties brought about by means of mechanical pro- cessing that reduces a substance’s viscosity, so that it does not return to its original viscosity until a later point in time. This means that the substance becomes thinner as the deformation takes effect. The change can be brought about in a number of ways—for example, by means of compaction, shaking or kneading. Everyday examples of substances that undergo this process include toothpaste and ketchup.
JOWAT INTERNATIONAL – USA A strong team to lead the Jowat Corporation: Achim Becker, Gerhard Haas and Marco Kubitza (left to right). Good Things Come in Threes An important cornerstone in our overseas activities, the Jowat Corporation has been key to Jowat’s international success. The appointment of the new Board of Directors gives some of the enterprise's most experienced players well-deserved recognition, while also allowing it to respond to current mar- ket demands. The members of the management team have already proven themselves many times over during their time at the enterprise. Here in Detmold, we have already seen how successful a three-person team can be in tack- ling the various areas of focus involved in run- ning an enterprise. The Jowat Corporation in North America is following this model, with three new managing directors in charge of the areas that best suit their respective strengths. Achim Becker joined the Jowat Corporation as IT Manager in 2000. His main tasks in this role includes the implementation and adaptation of SAP at Jowat’s locations in the Americas. He began gaining management experience in 2011 as managing director at Jowat de Mexico, and also as vice president for Controlling & IT at the Jowat Corporation. His new responsibilities as chief officer lie in Finance, IT and Production. Of the three new For the past few years, John Elder has been in charge of the Jowat Corporation’s sales in the north-east. managing directors, Gerhard Haas has been with Jowat for the longest. He has been acting as an overseas representative for the adhesives manufac- turer since 1989—initially as technical director, then later in other roles, such as vice president of Manufacturing and R&D. As chief officer for Human Resour- ces, Purchasing, Quality Management, R&D and Technical Service, he will now continue to pursue these areas of focus at the highest level. Jowat's US production site in High Point was first established in 1979. Marco Kubitza began preparing for his role in North America in 1995, taking up his first position there in 1996. He has been key in Jowat’s success in the region ever since, par- ticularly at sites in Canada and Colombia. Now that he has been promoted to chief officer for Sales & Marketing, his previous position as vice president of Sales will now be filled by John Elder. Mr. Elder has been with Jowat Corporation since 1997, initially as a repre- sentative and manager for sales in the North- east USA. He stepped into his new role in the summer of 2021. “John’s years of experience and ability to exceed our customers’ expecta- tions have without a doubt played a key role in our successful growth in the USA,” says Marco Kubitza. “He has proven a valued and dedica- ted member of our team, and we are delighted to support him in his position as head of our US Sales team.” 1515
MOBILE INTERIOR DESIGN MOBILER INNENAUSBAU Innovation on Tour Caravanning is a travel trend that is experiencing a spectacular comeback . What started as a more sustainable approach to holidays— domestic trips with a caravan or camper van are better for the envi- ronment than long-haul flights— has been stimulated further still by the travel restrictions imposed during the Covid-19 pandemic. In 2020, the demand for caravans and camp- ers was higher than ever among travel fans. As a result, both the lifestyle itself and the associated lightweight construction have be- come mainstream areas of interest. Leichtbau e. V. (igeL), a German interest group for light- weight construction, has been drawing up concepts to reduce weight for mobile interior design. Lightweight construction has plenty of benefits to offer caravanners. One obvious example of this is in terms of fuel—the light- er the vehicle, the lower its fuel consumption. This is a real selling point from both a finan- cial and an environmental perspective. Take a closer look at these sophisticated lightweight systems and another huge plus becomes clear. In Germany, if the total weight of the vehicle can be reduced to less than 3.5 tonnes, then a camper van or bus can be driven by anyone with a Class B driver's license—the same qual- ification required for a normal car. Combined Lightweight Expertise Together with partners such as Jowat SE, igeL has set up a “Mobile Interior Design” task force to select materials and construc- tion techniques specifically designed for use 16 For many, the caravan is the embodiment of free- dom and a flexible way of travelling.
in caravans and camper vans. Founded in 2019, this task force is split into the working groups “Requirements,” “New Materials and Technology”and “Standardization,” as well as a “Knowledge Database” that enables the va- rious igeL members to share their findings and experience. There is no competition here, as Peter Kettler of igeL explains: “Germany’s top three manufacturers of caravans are all members of igeL and act in their common interest. Our findings are also useful to man- ufacturers of yachts and custom vehicles.” In addition to industry experts, every link in the value chain is included in the process, in- cluding panel materials, surfaces and joining techniques. The latter is where Jowat—as an adhesives expert—comes in. In 2021, Klaus Kullmann, member of the Jowat Board of Di- rectors, was appointed Deputy Chair of igeL. “Different companies from the construction and furniture industries, higher learning institutes and many other areas all work to- gether on ways to optimize this technology,” explains Jowat Product Manager David Puls in summary. “This collaboration produces new production processes, which present entirely new challenges for the bonding technology in- volved.” Jowat SE relishes these challenges— after all, lightweight construction is a concept that is hugely important to our future. Modern concepts offer interior design possibilities that are both functional and lightweight. igeL, an interest group for light- weight construction in Germany, speaks for the many benefits of lightweight construction in various industries. Peter Kettler, managing director of igeL, explains the enduring success of lightweight construction. A STRONG NETWORK FOR LIGHTWEIGHT CONSTRUCTION What does igeL stand for? igeL is a lightweight construction interest group that was founded to promote and spread the idea of lightweight construction in interior design and the furniture industry. We bring together experts from research and teaching, business and the practical side of things. The association has about 90 members from the fields of mechanical engineering, the furniture and furniture supply industries, crafts and in- terior design, the caravan industry, furniture retail, research and development. Our strong network regularly carries out joint projects that result in new products, such as caravans and lightweight outdoor kitchens. The “Mobile Interior Design” task force is currently work- ing on many different issues, which I expect will also produce successful results. Why is lightweight construction so important? It helps to reduce the weight of vehicles, and offers benefits such as lower fuel consump- tion. Lightweight furniture is very sturdy, comes with interesting additional uses such as functional integration, and is easy to trans- port. It is also efficient in terms of resource consumption, as using lightweight materials can enable manufacturers to cut the amount of wood they need by up to 50 percent. 17
RESEARCH 18 SMALL BEINGS, BIG PLANS Humanity is living well beyond its means. What can we do to counteract our ever- increasing consumption of finite resources? There are many different promising projects underway—some of which are especially relevant to the adhesives industry. Join Jowat’s Research department and take a glimpse into the future.
»The bacteria are being cultivated specifically for this purpose.« Dr. Hartmut Henneken, Research Services Every year, we are reminded at earlier and earlier dates that our planet’s resources are finite, and we are using them up at an increas- ingly fast rate. Earth Overshoot Day marks the date by which the Earth’s population has prematurely used up all the raw materials that can be reproduced in the space of one year. In 2021, this point was reached on 29 July—a new, tragic record. In addition to the long-term need to stop consuming fossil raw materials, it is therefore also important that we uncover new, regenerative resources that can be used to cover our growing demand in all walks of life. as the basis for new products,” he says. However, if the company focuses too much on extracting these proteins from peas or soya, it runs the risk of getting into a com- petition with the food industry, where such ingredients are increasingly being used to make vegetarian and vegan meat substi- tutes—products that have also seen a huge increase in demand in recent years. So what routes can Jowat look into instead? One cheap alternative that can also be produced in large quantities might be polylactide—a synthetic polymer made using lactic acid generated during biomass fermentation. Researchers are always working on future-proof con- cepts for extracting raw materials. Sophisticated Ideas So what does this mean for the adhesives industry? The majority of the adhesives available on today’s market are (still) based on fossil resources such as petroleum. How- ever, Jowat has been working tirelessly on finding alternatives for many years, and with its Jowatherm® GROW and Jowatherm- Reaktant® GROW products has already launched two series of adhesives that are made partially from organic-based raw ma- terials—in a percentage that still keeps on growing. The most important base materials for these products include substances such as crude tall oil, a by-product from the pa- per industry. But with demand on the rise, even a product like this isn’t always avail- able. As such, we need to be flexible and work on additional potential sources, rather than sticking rigidly to any one path. But as Christoph Funke of Jowat’s Research and Development department is keen to stress, this is easier said than done. “It’s true that Jowat has already concluded research proj- ects that looked into using plant proteins In fermentation systems such as these, the useful microbial creatures go about their important work. 19
RESEARCH Leftover agricultural substances are partic- ularly well-suited to use in this process, and would help us avoid getting into competi- tion with food manufacturers. Polylactide is a promising material that is already being used as a plastic. As the basis for an adhesive, however, it still displays structural weak- nesses, as Dr. Carmen Plass from Jowat Research Services department explains. “Poly- lactides are more brittle than other plastics, and an adhe- sive based on this substance would not be as resistant to heat as hot melt adhesives made from other materials.” As such, bonding using a polylactide-based adhesive would be unlikely to satisfy the high standards Jowat and its users have come to expect. “However, Jowat is already dedicating a lot of resources to researching formulations and modifications that could be used to optimize the proper- ties of a polylactide adhesive,” she stresses. Such a product could conceivably be used in the paper industry, as well as the timber and furniture industries, which are among the biggest markets for Jowat adhesives. A New Bonding Culture? Microbial biopolyesters such as polyhydroxybutyrate (PHB) represent another particularly promising solu- tion. These biopolymers, which are formed using bacteria, are biologically degradable. Several known bacterial strains, such as pseu- domonas and bacillus, can produce this sub- stance—in fact, some of them are trained or cultivated specifically for this purpose, while others are created by means of genetic modifi- cation. Metabolized PHB can only be produced through cell lysis, whereby the synthesized raw material is released into the medium so it can be extracted. Dr. Hartmut Henneken, head of Research Services at Jowat, believes that the ability to develop these types of bac- 1820 terial strains opens the door to a number of new possibilities. However, there is an inter- mediate stage required for the manufacture of PHB-based adhesives that is currently pro- viding a stumbling block to further progress. “The PHB needs to be used to make polyes- ter urethane (PEU), which we can then use in turn to make adhesive. But there aren’t enough companies right now who produce PEU in large quantities.” As a result, the amounts available are not enough to cover the demand of a large manufacturing enterprise such as Jowat. “However, the availability of PHB is steadily improving, so a lot of new possi- bilities are opening up for man- ufacturers of raw materials.” This setback has not stopped Jowat from pursuing the idea of bacterial strains—in another endeavor, the adhesive expert has commissioned Phytowelt GreenTechnologies GmbH to develop bacterial strains that produce resin acid compounds by means of genetic modifica- tion. Resin acids are an import- ant component in many adhe- sive formulations. However, up until now, it has taken a huge amount of physical labor in Brazil and China to extract the necessary resins, and fluctua- tions in quality have also been an issue. A standardized syn- thetizing process using special bacteria could simplify workflows and enable use to maintain a consistently high level of quality—without having to rely on a means of obtaining raw materials that is easily com- promised. “We’re still very much at the start of this journey though,” says Dr. Daniela Klein of Research Services. “The synthetic resin acids we have produced so far have been sufficient for lab analyzes, but we have a long way to go before we can begin conducting practical tests.” Nevertheless, Jowat SE won’t be giving up on these efforts just yet, and the company intends to consistently continue pursuing its august and ambitious research goals. This is how it might look under a microscope when the bacteria are metabolizing sugar to create the coveted adhesives. (Photo by Elisabeth Ingolić).

JOWAT NEWS News from the World of Adhesives The world of adhesives is always evolving. Trends and innovations define what direction the industry will take in the future. So what’s new at Jowat and in the adhesive expert’s diverse portfolio? Read on for exciting bulletins on products, personnel and awards. AN AWARD- WINNING PROJECT A TOP-QUALITY ADHESIVE SUCCESSFUL DEKRA INSPECTION Together with its industrial and research partners, Jowat has developed an adhesive system that will help to make the produc- tion of silicon plates for solar panels more sustainable (see Jowat Magazine 2021). The “New Beam” project has received the Plas- tics Innovation Prize for 2021 in Germany’s Ostwestfalen-Lippe region. The jury were impressed by the clever way the project combined a reusable plastic beam, on which the silicon blocks are fixed in place during sawing, and an adhesive that is easily soluble, yet still reliable. Dr. Harmut Henneken from Research Services accepted the coveted award on behalf of Jowat SE. The research project was completed successfully some time ago, and is now in development. Negotiations with potential users and produc- ers regarding a market launch are currently underway. The RAL seal of quality indicates a product of high quality, helping customers to nav- igate the market. With the Jowatherm- Reaktant® 604.35 adhesive for window pro- file wrapping, customers in this sector know they can place their trust in Jowat. The RAL mark is a certification of high qual- ity for plastic window profile systems. In order for a profile to achieve this standard, the adhesive used in its production also needs fulfil the appropriate requirements. Jowatherm-Reaktant® 604.35 passes this test with flying colors—the adhesive is perfect for wrapping plastic profiles with the PVC- and PMMA-based films commonly used for decorative purposes (in combination with a Jowat® primer). The combination of high ini- tial strength and a short setting time provides the perfect platform for outstanding profile wrapping results. In September 2021, Jowat’s management systems, which are certified in accordance with ISO standards, were reviewed by a new certifying agency: DEKRA. All the certificates were extended accordingly. Four Jowat locations were inspected and assessed with regard to their existing certi- fications. After finding no deviations from the requirements, DEKRA extended the cer- tificates, thereby confirming once again the high working standards at our locations in Detmold (ISO 9001, 14001, 50001), Elsteraue (50001), High Point (9001) and Bandar En- stek (9001). Member of the Board of Directors Dr. Christian Terfloth accepted the certificate from Frank Barenscheer of the DEKRA Man- agement Board a few weeks later. Barenscheer also praised the cooperation: “Jowat has prov- en once again that it is able to successfully tackle the dynamic requirements in its global sphere of competition.” 19 21
APPLICATION – ROOF LININGS Roofs need to hold up for decades against the full spectrum of ele- ments—from water to wind and fluctuations in temperature. Under One Roof Roof linings remain more or less invisible for the entirety of their lifecycle—yet they are key to the weatherproofing and energy properties of any roof. Just like other construction materials, it is their intrinsic values that guarantee these functions—such as top-of-the-range adhesives from Jowat. 20 22
Energy efficiency in buildings is becoming an increasingly important issue. But it’s not just older buildings that need to be brought in line with new energy standards. High-quality construction materials and design are also of the utmost importance for new buildings, as they represent the only way of ensuring reliable insulation and therefore low energy consumption. Roof linings—an additional layer under the out- er roof covering—provide improved protection against the elements. While designs that use laminates provide excellent protection against wind and moisture and good energy insulation, breathable textile membranes allow for good air circulation, which helps to prevent mold. Finding the best combination of materials for any lining also depends on the individual in- stallation situation—the requirements for a butterfly roof differ from those for a pavilion roof, for example. On top of this, choosing the right adhesive can help to ensure that the lin- ing and the protection it offers last for longer. Top Adhesives for Top Performance Membranes and laminates such as the un- derlays used in the construction industry are highly demanding in terms of an adhesive’s adhesion properties. The most common type of adhesive used for bonding construction textiles is strong PO hot melts. While the ad- hesive is applied over a large area when us- ing a laminate, coating a textile membrane requires an “open” application technique. Jowat-Toptherm® 230.45 is an adhesive de- signed for this application that has been on the market for several years. Just like in other industries, the construc- tion sector is seeing a trend towards polyure- thane adhesives that can also reliably hold up to the demanding requirements placed on the laminate—with short cycle times, a wide adhesion spectrum and high final strength, they open the door to a wide range of optimization options when it comes to coating roof linings. PUR hot melt adhe- sives are the perfect choice for moisture- resistant bonds that also need to be able to Just like in other industries, there is a trend towards polyurethane adhesives. Despite being all but invisible once they have been laid, roof linings need to be able to with- stand a number of different factors. withstand mechanical loads for a long time. A certain amount of flexibility in the bond reduces the risk of damage in such scenari- os. The lining remains reliably watertight— which means the roof does, too. Looking to the Future One promising candidate for effective use in the field of construction textiles is the PUR hot melt adhesive Jowatherm-Reaktant® 630.20. Due to its low-viscosity formulation, this product can be used to achieve a smooth, continuous film of adhesive even with a low application amount—a characteristic that is of high value to processors. This adhesive can also be used in industrial mass-production processes. Whether processors choose a PO or a PUR adhesive, Jowat supplies suitable and reliable bonding solutions that will put a safe roof over your head in both scenarios. Jowatherm- Reaktant® 630.20 i Polyurethane hot melt adhesive with good initial strength and high cohesion Jowatherm-Reaktant® 630.20 is notable for its low viscosity, which means that it flows evenly and seals effectively even when applied in small quantities. Specially developed for coating construction textiles 2123
JOWAT INTERNATIONAL – MALAYSIA A STRONG LOCATION Originally founded in 2000 as a sales organization for Malaysia and Singapore, it quickly became clear how important Jowat’s strategically located subsidiary in Malaysia could be to the enterprise. More than 20 years later, it is now one of the fundamental pillars of Jowat SE in the Asia-Pacific region. 22 24 Jowat’s manufacturing location in Bandar Enstek has been growing rapidly ever since it was first founded.
The fact that the location in Malaysia has its own Research and Development department gives it a special edge. The Petronas Twin Towers are the world-famous symbol of Kuala Lumpur, the capital city of Malaysia. More Than Just a Subsidiary Jowat’s Malaysian location is surrounded by booming markets, and can effectively serve as a hub for all the enterprise's activities in the Asia-Pacific region. The in-house pro- duction facility enables Jowat to cut both lead times and the administrative burden. Dr. Ralf Schelbach, vice president for Asia- Pacific, has been stressing the importance of the location to Jowat since as far back as 2015: “Malaysia is not an extension of our workbench, but an independent location and bridgehead, where we are also undertaking product R&D in order to provide the highest level of satisfaction for the requirements of local customers.” Those requirements extend far beyond geographical and cultural proxim- ity and a common time zone for easier com- munication with customers, and also include the ability to cater to specific requirements in areas where the local market differs from the European one. All in all, Jowat Manufacturing is a success, as demonstrated by its ongoing growth. “Our focus was originally on the Asia- Pacific region,” says Managing Director Willi Wiens, “but more recently we have also been catering to the markets in South America, Africa, Russia and Turkey.” Upholding Established Quality Standards The new markets also open the door to new product categories to be researched and fur- ther developed in Bandar Enstek. Here too, geographical and cultural proximity provides an advantage, as Willi Wiens explains. “As the long arm of Jowat SE, we are able to overcome linguistic and organizational hurdles more easily by virtue of our local presence.” Despite the location's distance from the enterprise's headquarters in Detmold, its customers know that there is one thing they can rely on: “When it comes to our technology, products and pro- cess quality, we are a fully integrated part of the Group, so everything we do is in line with the long-establish Jowat quality standards.” 23 25 Just five years after the sales organi- zation, a Malaysian production company was founded with a focus on manufacturing water-based dispersion adhesives. To keep up with the growing demand, in 2009 the sales organization and the manufacturing companies were brought together under one roof at a single, larger facility. At the same time, hot melt adhesives were added to the production portfolio. In 2015, the two branches of the company were merged to form Jowat Manufactur- ing. Yet even with the capacity this gave them, it wasn’t long before more resources were required to cater to the demand for optimum bonding solutions in the local Asia-Pacific market. Over the course of just 14 months, a new manufacturing site was built in Bandar Enstek. The opening ceremony was held in 2015, and the plant provided a significant boost to capacity for hot melt adhesive production, adding reactive hot melt adhesives, solvent-based adhesives and water-based primers to the portfolio. Bandar Enstek is one of Jowat SE’s most modern manufacturing locations, and is now home to a multi-cultural team of around 120 employees.
AXIA BEST MANAGED COMPANIES TWICE AS NICE: AXIA BEST MANAGED COMPANY 2021 For the second time in a row, Jowat has received the “Axia Best Managed Company Award” for successful companies from the German Mittelstand—another milestone in a business year filled with both challenges and opportunities. What are the secret ingredients that make a German Mittel- stand company a success? In order to win the Axia Best Man- aged Company Award, aspiring companies must prove their cre- dentials in four areas: strategic vision, innovative power, sus- tainable corporate culture, and good business management. Following on from its first award in 2020, Jowat SE has now been placed among the proud win- ners of the Best Managed Com- pany title for the second time. The Axia Best Managed Com- panies (BMC) programme is a competition run by Deloitte Pri- vate, WirtschaftsWoche, Credit Suisse and BDI, and acts as a hallmark of quality for success- ful enterprises from the German Mittelstand. The coveted award is now presented in more than 30 different countries. Valuable Conﬁrmation “We are incredibly honored to win the ‘Best Managed Com- pany’ award again,” said a de- lighted Ralf Nitschke, member of the Jowat Board of Directors. “This confirms that we are on the right track in terms of the strategic, sustainability-orient- ed way in which we treat our employees and business partners.” Like countless other com- panies, Jowat’s 2020 business year was over- shadowed entirely by the Covid-19 pandemic and the resulting challenges. After a year like that, an award like this feels even more import- ant than usual, as it confirms that, where others might have stumbled, Jowat has instead seized the opportunities present to it with gusto— and obviously made some good choices in doing so. “It’s companies like Jowat that don’t just weather the pressure during extraordinary times such as these—they allow it to trans- form them into their ultimate form,” explains Mischa Tschopp, Market Group Head for Ger- many and Austria International at Credit Suisse. “It is thanks to them that crises can herald a new dawn. In the face of an increased sense of urgency, they recognize new develop- ments such as digitalization and sustainability and find ways of implementing them to the benefit of our society.” The way in which the Detmold-based adhesives experts have han- dled the pandemic’s impact on their day-to-day business (see page 34) and the company’s more than satisfactory returns for the 2020 business year are impressive examples of what it means to be the Best Managed Company.

JOWAT CLASSICS JOWAT CORPORATION C l a s s i c s On every channel: The Jowat Classics campaign is available to admire on LinkedIn and Jowat.com. Timeless: Jowat Classics You don’t survive more than 100 years in an industry without seeing a lot of products come and go. Like many other companies, Jowat’s product range is constantly evolving to keep up with the latest trends and further improve the performance of its adhesives. Nevertheless, the hundreds of adhesives in our portfolio still include a few classics without which our world just wouldn’t be the same. A consistent product range is a mark of quality for a company with a long-standing tradition. And here at Jowat SE, we’re no different. We set great stock in ensuring that we never take established and proven products off the mar- ket without replacing them, as long as they are still in demand and in line with the latest technological standards. But being driven to innovate is also a valuable characteristic for any manufacturing enterprise that wants to make its mark on the market. Ingo Horsthemke, head of Product Manage- ment and Marketing at Jowat, is well-versed in the balancing act the adhesive experts have to manage every day. “On the one hand, it’s very important to us to keep developing our prod- ucts further and coming up with innovations to impress the market. But at the same time, of course, there are certain classic adhesives that form the cornerstone of Jowat’s success.” »The Classics series covers a huge range of different products.« Ingo Horsthemke, Head of Product Management and Marketing One such product is the unfilled EVA hot melt adhesive Jowatherm® 280.30 for edge- banding, which has been a constant in the enterprise's portfolio since the late 1990s. The fact that this adhesive remains so pop- ular more than 20 years later is testament to its timeless high quality. In light of such achievements, we have decided to honor this and other evergreen products from the Jowat portfolio in a category reserved for the crème de la crème of adhesive formulations: 2021 saw the launch of the Jowat Classics sec- tion on the Jowat SE website and LinkedIn page. “ Our Classics series covers a huge range of both chemical product groups and app- lications,” Ingo Horsthemke is keen to stress. And the range keeps on growing, too—as recen- tly as the turn of the year, more Jowat products were awarded the “Classics” moniker and ad- ded to the echelons of timeless and outstan- ding traditional adhesives. 25 27
APPLICATION – VEHICLE CONSTRUCTION The Car’s New Clothes The idea of what mobility means is changing more than almost any concept in the world right now. In order to ensure the survival of the car, its design, safety measures and drive technology need to be adapted further and further to keep it in line with future trends. The adhesive applications for which Jowat provides solutions also have an impact on this process. Application Technology Specialist Florian Krüger provides an insight into the latest developments in this field. The car of the future requires a new take on bonding solutions from Jowat. i Filter bonds for engine intake ﬁlters, active carbon ﬁlters, pollen ﬁlters The future of individual mobility is equal parts uncertain and exciting. While hydrogen and electric motors promise a significant reduction in CO2 emissions, smart techno- logies—particularly autonomous driving—offer greater convenience and safety for the occupants of the vehicle. Both these fields will result in fundamental changes to the way vehicles are built—of this, Florian Krüger is cer- tain. “As it stands, vehicle cockpits are designed entirely with the driver and functionality in mind,” the Jowat SE application technology specialist explains. “If vehicles no longer need to be controlled manually, that means modules like the steering wheel and the gearstick can be done away with entirely.” New forms of drive technology will also create more space in the vehicle—the central console can be removed, for example, as it mainly exists due to the combustion engine. Up-and-Coming Materials For Jowat, this means that the way adhesives are used in vehicles also needs a rethink. The inte- rior of the future will place greater emphasis on design and allow for more intuitive use. This will lead to new materials—and, in turn, new bonding solutions, which Jowat is working with manufacturers to develop. One example of this is the touch-operated console of the future, which will require a coating that maintains the transparent quality of the surface. Other components of the car will also present a constant stream of new challenges in terms of compatible adhe- sives. “One German car manufacturer has been using high 26 28
quantities of recycled materials for the seat covers in one of its models,” says Florian Krüger. “One of the factors that is important when bonding these is the purity of the recycled ma- terial.” The use of renewable raw materials in vehicle interior design is also on the rise. NFPP is based on a combination of natural fibres and polypropylene, and its minimal weight makes it of particular interest for lightweight con- struction. Its feel and noise insulation proper- ties have also received positive feedback. Non-Hazardous Adhesives for the Future In order to make car design more sustainable in every way, an environmentally friendly bonding solution will also be required. In the Jowatherm-Reaktant® MR 642.90, the adhe- sives experts have provided a monomer-re- duced—and therefore not subject to hazard labelling requirements—PUR hot melt for coating vehicle interior design. “This adhesive can be used in all the conventional application procedures, though its greatest strengths are its sprayability and its suitability for 3D coating,” Florian Krüger underlines. It should also be noted that, by using this product, companies can help to improve the health and safety of their employees (see page 13). Florian Krüger calls the Jowatherm-Reaktant® MR 642.90 “a true all-rounder when it comes to coating components,” and one that fulfils all the requirements for modern production. It encapsulates perfectly Jowat’s ability to pro- vide its customers with modern solutions, and is the perfect companion on our road to the future of mobility. i Coating for dashboards, A, B and C pillars, supports, central door panels, arm rests, map pockets i Textile coatings for seat covers and rooﬂights Spacious and comfortable: The car of the future will have much less emphasis on functionality. i Trunk bonds for loading beds and partition blinds 27 29
SUCCESS STORY All-Rounders in Filter Production The filter industry has been experiencing a boom for several years now. Cars, ventilation systems, air purifiers for the removal of pol- lutants and germs from ambient air… filters are used everywhere, in all shapes and sizes. Jowat is well-versed in catering to the require- ments of different types of filters while also helping to ensure user safety. Wherever they are used, all air filters per- form the same function: keeping the ambi- ent air clear of unwanted foreign particles, contaminants and germs. The difference is in the details. For instance, filters in air puri- fiers for indoor use protect primarily against fine dust, pollen, bacteria and other volatile media, such as odors and gaseous substances like benzene and ozone. In industrial facili- ties, on the other hand, coarse dust and gases need to be filtered out so people don’t breathe them in, as they can be damaging to their health. The larger the volume of the space that needs purifying and the more substanc- 30 30 »The filter industry is gaining in importance. And with it, so are optimized adhesive solutions.« Michael Dressler, Product Manager es in the air, the higher the required filter capacity. The high filtration level that, for many years, was used mainly in clean rooms and industrial applications has gained new significance as a result of its effectiveness against the novel coronavirus, and is now be- coming more common in everyday applica- tions. Stricter occupational health and safety measures, a desire for healthier living spaces, the need to reduce the risk of infection—all these requirements, and many more besides, mean that the demand for Class H14 to U17 HEPA and ULPA filters will increase signifi- cantly over the next few years.
Hard to believe: Filter media such as these can contain several kilograms of adhesive. What does HEPA/ULPA mean? HEPA stands for ‘High-Efficiency Particulate Air’ filter. HEPA filters are found in many everyday items, such as air purifiers and vacuum cleaners. ULPA (Ultra-Low Penetration Air) filter is the term used to designate a class of filter that is only used in facilities such as research labs and hospitals, and needs to comply with the strictest of hygiene require- ments. A Non-Hazardous All-Rounder What is the most effective way to build a filter medium that is able to provide a filter capac- ity of up to 100,000 cubic meter in a small space? For this purpose, non-woven and nee- dle felt filter media are given upgrades such as a polytetrafluorethylene-based membrane and anti-static properties, and made resistant to both oil and water. Folding and pleating the filter medium significantly increases its surface—and thus its filter capacity. This pro- duction step requires not just the utmost care, but also an outstanding bonding solution that guarantees both fine application and reliable adhesion, right from the start. In these con- ditions, there is absolutely no scope for cut- ting corners when it comes to the adhesive’s performance. The new Jowatherm-Reaktant® MR 614.50 is the perfect choice for this appli- cation and many more involved in the man- ufacture of filter media. A true all-rounder, it isn’t just used for pleating— it is also suitable when coat- ing the filter medium, facili- tating low application quan- tities and outstanding results both for active carbon binding and when bonding multi-lay- ered filter media. The combi- ned use of this versatile adhe- sive can make production pro- cesses much simpler. Target: Innovation Due to its monomer-reduced formulation, the PUR hot melt with hazard-free labelling is eas- ier to use than similar products. Unlike many reactive adhesives, With adhesive solutions such as Jowatherm-Reaktant® MR 614.50, Jowat is catering to the growing filter production market. Michael Dressler Dipl-Ing. | Product Manager Michael Dressler’s main area of focus is bonding solutions for the manufac- ture and joining of filter media. MR formulations are not subject to hazard labelling and the resulting training require- ments that will soon come into effect. Another benefit provided by these new alternatives is that they can be processed at low temperatures of 100–120°C, which not only saves energy but also improves safety during the bonding pro- cess. This adhesive has a lot to offer—especial- ly when you consider how important the indus- try is going to become over the next few years. In light of the filter industry’s increasing relevance in all areas of our society, bonding solutions that are suitable for applications in this sector will likewise have an important role to play. Jowat is always on hand to sup- port its customers in the filter industry with innovative adhesives and expertise—which is why it also has new developments for optimizing the coating, pleating and frame bonding processes in the pipeline for the next few years. 31
SUCCESS STORY Step by Step Nolte Küchen GmbH & Co. KG is one of Germany’s most successful kitchen manufacturers. Local innovation and high quality are the guiding principles of the company with a long history from Löhne, in Germany’s Ostwest- falen-Lippe region. As such, it’s no surprise that they chose Jowat, an enterprise based just 30 kilometers away in Detmold, as their adhesives partner—at least you wouldn’t think so. In fact, the close and successful partnership the two businesses enjoy today is the result of a very gradual process. Today, 64 years since it was first founded, Nolte has almost 1,300 employees. Today, Nolte Küchen and Jowat SE can look back on a long history of cooperation as part- ners—perhaps even friends. It all began in the 1980s when the kitchen manufacturer procured its first products from Jowat—the Jowacoll® 110.00 assembly adhesive, an adapted Jowatherm® 288.xx series EVA hot melt adhesive for edgebanding, and a plastics adhesive for small repairs. Wolfgang Rasser, who handled all our dealings with Nolte at the time, was given the opportunity to demon- strate his expertise and the quality of our ad- hesives many times over the years. “At first though, it was always just little questions to do with their bonding processes,” he stresses. “But the scale and complexity of the enquiries increased as time went on.” Things finally got serious in 1990, with what would become an absolute sensation within the industry. Nolte was planning to switch its adhesive to a polyolefin-based (PO) product supplied by Jowat: the Jowat-Hightherm® 227.01 (listed at the time under the name 32 30 EP 603553). “Nolte was possibly one of the first manufacturers in the world to use PO for edgebanding,” Wolfgang Rasser muses in retrospect. The first trial run was conducted at the customer’s site in 1991. When put to the test on a double-sided IMA edge laminating machine, the PO hot melt adhesive outshone the product Nolte had previously been using. The changeover was given the green light after an independent LGA test confirmed that the Jowat-Hightherm® 227.01 was the better adhesive for the application in question. A Fast Response Meets Great Dedication The next contract was soon to follow, as the customer asked Wolfgang Rasser to oversee the switch from several products to Jowat alternatives at once. He still recalls today how much of a mammoth task this was: “I spent several days at Nolte Küchen during that period.” Thanks to the close coopera- tion between the kitchen manufacturer and the adhesive expert, the changeover was a complete success. Whenever the customer expressed any doubts regarding the adhe- sive’s performance, Jowat’s Support team was always on hand to clear things up. This level of service played a significant role in strengthening the business relationship. “The fast response times and great dedica- tion demonstrated by our contacts really in- creased our trust in Jowat adhesives,” recalls Hans Flügel of Nolte Küchen’s Development and Design department. On the basis of this trust, more and more orders came in from Nolte—including one for a batch of Jowacoll®
Nolte Küchen trusts in Jowat’s reliable adhesive solutions, especially when it comes to edgebanding. Founded in 1958 in Löhne, North Rhine-Westphalia, the company had 70 staff when it first started out. Its factories there and in Melle, Lower Saxony, provide a total of 100,000 m2 of production area. The company produces around 880 kitchens per day, Today, almost 1,300 employees work at Nolte Küchen. Nolte kitchens are popular for their ‘Made in Germany’ quality, and are exported to more than 60 different countries. dispersion adhesive delivered in small bottles that would be easy to transport and use for on- site kitchen installation for Nolte’s customers. Nolte now also uses Jowat adhesives for the automated bonding of handle strips—the colorless PUR hot melt adhesive Jowatherm- Reaktant® 608.00 and the Jowacoll® 114.80 adhesive, to be precise. Nolte and Jowat are also embarking on new endeavors together. Following the conversion of a single-sided Homag system at Nolte’s Löhne site in 2015, the kitchen manufacturer became one of the first companies to process the PUR hot melt adhesive Jowatherm-Reaktant® MR 607.90 with hazard-free labelling. Unwaning Enthusiasm and Interest Hans Flügel (middle) at the Jowat Symposium 2016. Both enterprises value the long-standing busi- ness relationship—which has since grown to become more of a friendship—and work tire- lessly to keep it healthy. “Nolte representatives like Hans Flügel have always been enthusiastic participants in the Jowat Symposium,” says Wolfgang Rasser, emphasizing the kitchen manufacturer’s loyalty. The business rela- tionship between Nolte and Jowat has now been passed on to the next generation: Daniel Hass has stepped into Wolfgang Rasser’s shoes as our Nolte Küchen liaison, while Head of Purchasing Johannes Heitmann is now the key man in maintaining the good partner- ship with the adhesive experts on the Nolte side of things. “We look forward to seeing what joint projects 2022 and the years beyond will bring,” says Heitmann, looking to the future. 3133
A NEW WAY OF WORKING Digital on-boarding: for a long time, most of our colleagues were only able to connect to one another online. 34
FULL STEAM AHEAD THROUGH THE PANDEMIC When the Covid-19 pandemic broke out in 2020, its impact was felt by every business in the world. At Jowat SE, like at many other companies, our every- day work lives were turned completely upside-down. So how do you follow infection prevention regulations while also keeping your regular business ticking along? The Detmold-based adhesives experts have proven that you can do it all—you just need everyone at the company to pull together. For many companies, working from home has become the new normal. Here at Jowat, too, it quickly became clear that some of our staff would need to move their office space— so mobile working was introduced. Since almost everyone working in these depart- ments has a laptop or ThinClient, they were able to switch to working from home in the spring of 2020. Thanks to the likes of Skype and Microsoft Teams, the workflow has been able to continue full steam ahead, with docu- ments being shared online and meetings held in the form of video conferences. A New Way to Work—Both Analogue and Digital “It took a little while to get used to, but we’ve now successfully got everyone working from home,” says Nina Hilgenberg, head of Person- nel Development at Jowat. However, no-one has had to move away from their desk per- manently—instead, the staff switch regular- ly between working from home and coming into the office. The situation is similar at our overseas companies, as confirmed by Gerhard Haas at the Jowat Corporation in High Point. “We’ve made it possible for most of our office staff to work from home. The sudden change was a challenge for our IT department, but one they overcame admirably.” In addition to this, extensive cleaning and sterilization procedures have been implemented, social distancing rules introduced, and the wearing of masks made mandatory. Needless to say, mobile working is trickier for staff in our production departments and labs. In addi- tion to following the conventional hygiene concepts, the most important factor in re- ducing contact between employees in these areas is flexibility. “We’re leaning more heavi- ly on the concept of staggered working hours,” Mrs. Hilgenberg explains. This means that shift times have been offset to ensure that as few people as possible come into contact with one another at the machines and in The Jowat Hygiene Concept Staggered working hours help to keep the numbers of employees who come into contact with one another during shift changes to a minimum. Administrative staff regularly switch between working from home and coming into the office. In January 2021, Jowat set up its first in-house test center. In summer, the company doctor at our location in Detmold made the coveted vaccine available to all our employees. Staggered working hours helped Jowat staff reduce in-person contact—and therefore the risk of infection. the changing areas. The time workers are per- mitted to spend on site before and after their shifts has also been reduced to a minimum. In January 2021, we set up our own test center at the House of Technology in Detmold so that staff can get tested for the virus at work. The center carries out over 2,000 tests per month, and also tests external service pro- viders who have appointments and meetings on the Jowat premises. Our company vacci- nation drive has also been running smoothly. “We set up a vaccination programme with our company doctor in early summer,” Nina Hilgenberg continues. Everyone who wanted the vaccine had got it by August. Additional On-Site Safety So, what’s next? The pandemic has brought concepts and ideas to the fore that can also be incorporated permanently into the way we work. “Our staff will still be able to work from home or elsewhere in the future. They value the extra flexibility and not having to com- mute,” Mrs. Hilgenberg explains. “With that in mind, we have come to an agreement that will ensure mobile working is still possible even after the pandemic has passed.” Another positive inherited from the pandemic comes in the form of the training videos that explain concepts such as how to use digital commu- nication channels and time logging systems. Like mobile working, this concept has also proven so successful that Jowat will contin- ue to develop further tutorials for everyday processes and software in the future. Gerhard Haas at the Jowat Corporation takes a similar view: “We’ve learned a lot about how to im- prove efficiency in virtual meetings.” In light of these positive experiences and the numer- ous benefits of these new approaches, it’s safe to assume that communication at Jowat will continue to be more digital in the future. 35
