One-component, moisture-curing PUR hot melt adhesives have been an established technology in the wood and furniture industry for several decades.
In general, conventional PUR hot melt adhesives have an excess of free monomer isocyanate (usually 4-4‘-diphenylmethane diisocyanate – short MDI) in the order of approx. 2 %. Since 2012, products containing isocyanate which have a free monomer isocyanate content of 0.1 % or more need to be labelled with the GHS hazard pictogram No. 8 (health hazard) and the relevant safety information (H and P statements). Adhesives with a free monomer isocyanate content below 0.1 % are not subject to labelling restrictions with regard to hazardous substances.
Jowat has already been working successfully on alternative technologies which are below the limit of 0.1 % since the beginning of the 21st century.
The Jowatherm-Reaktant® MR (monomer-reduced) product group from Jowat provides several PUR hot melt adhesives for a wide range of applications which are not classified as hazardous substances. The portfolio has now been expanded and a premium product for highest demands in edgebanding has been added as a complement to the established general-purpose product Jowatherm-Reaktant® MR 607.90/91.
In addition to the high-quality bond at “PUR level”, the new unfilled PUR hot melt Jowatherm-Reaktant® MR 608.90 also impresses with a colourless adhesive film. This facilitates very thin, barely visible bondlines for attractive furniture fronts – especially on furniture with dark decor materials or high-gloss surfaces. To meet the requirements for the unbroken trend in the furniture industry, Jowat also supplies Jowatherm-Reaktant® MR 608.91, a pure white colour version for white and very light decor materials.
Jowatherm-Reaktant® MR 608.90/91 is an adhesive for automatic edgebanders. Wide range of applications, e.g. for edgebands made of pressure laminates, polyester, PVC, ABS, PP, resinated paper, solid wood, or veneer.
