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., Wood conveys a feeling of well-being as a natural material and can have a positive effect on the atmosphere of a room.
High-performance adhesives play a key role in the manufacturing of parquet and ensure high quality and durable floors. In our portfoglio, we have several modern reactive dispersion and hot melt adhesives which meet different requirements for bonding of solid wood layers with the top layer. Best suitability of the adhesive 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 with a neutral pH value.
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.
Depending on the intended purpose and the requirements for the floor, our portfolio provides a wide range of products from D3 dispersions for interior use with short-term exposure to water according to EN 204/205 to D4 dispersions for interior use with frequent long-term exposure to running water or to reactive PUR hot melts for highest visual and technological demands.
