In interior design, parquet floors stand for premium quality, permanent durability and superior appearance. The large variety of different forms, colours and wood species facilitates bespoke products. As a natural material, wood conveys a feeling of well-being and can have a positive effect on the atmosphere of a room.
High-performance adhesives play a key role in the manufacture of parquet and ensure high-quality and durable floors. Jowat has developed several modern reactive dispersion and hot melt adhesives which meet the different requirements for the bonding of the solid wood layers with the top layer. Which adhesive will provide the best results depends on several factors, such as the wood species used for the substrates. For instance, certain wood species tend to discolour when bonded with acidic adhesives. This is prevented with special D3 dispersions from Jowat with a neutral pH value. An additional benefit from these adhesives is the low corrosiveness, which reduces the wear and tear of the production equipment to a minimum.
Further criteria which have to be taken into account when a suitable adhesive is chosen are the origin and the storage conditions of the wood, and the material mix of the product. For instance, it is essential to know whether the wood is rich in resins, has a high moisture content or has already been dried, or if it contains metal ions which could lead to a reaction with the adhesive. The structure of the wood also plays a role, as well as whether there are any differences in the tension of the wood and whether preserving agents have to be added to the dispersion. Modern reactive dispersion adhesives are characterised by high yield, short pressing times, elastic bondlines and a wide range of processing methods. Jowat supplies dispersions with a broad spectrum of viscosities for the different application procedures and surface properties.
Depending on the intended purpose and the requirements for the floor, the Jowat product portfolio provides a wide range of products, from D3 dispersions for interior use with short-term exposure to water or high humidity according to EN 204, and D4 dispersions for interior use with frequent long-term exposure to running or condensed water as well as for exterior use with an adequate surface coating, to reactive PUR hot melts for highest visual and technological demands. A sound know-how regarding the different components in the process chain and how they may affect the adhesive and the bonding result is of utmost importance during the selection of the adhesive to provide tailored solutions for the most different applications.
