Adhesive raw materials based on polyurethanes and polychloroprens allows a long furniture life
In applications like the lamination of furniture surfaces with films and the bonding of foam parts for upholstery furniture the adhesives to be used need to fullfill demanding requirements. Durability, mechanical resistance, but also environmental safety and aesthetics are indispensible properties for the adhesive. Bayer MaterialScience offers a large portfolio of water-based and solvent-free - and therefore environmentally friendly - raw materials based on polyurethanes and polychloroprens. These products can be formulated as one- or two-component adhesives.
Some application examples:
Lamination of fiberboard with decorative film for furniture fronts and surfaces in 3D-press application
Foam bonding of upholstery furniture and matresses
Parquet adhesives
Adhesives for 3D-lamination of furniture with Dispercoll® U and Desmodur® D
Adhesives based on polyurethane dispersions are processed by high temperature activation. This process can be applied for the lamination of decorative films on fiberboard fronts, to name just one example. During the so-called 3D-lamination process the adhesive is applied to the fiberboard and after drying a pre-heated decorative film is pressed under vaccuum to the board. A typical application is the bonding of kitchen cabinet doors. More on thermo-activated adhesive raw materials here.
Another processing option for the 3D-lamination process are latent reactive dispersions. These are adhesives that are processed as a one-component system, yet they show the properties of a typical two-component system. Latent-reactive adhesive dispersions consist of a polyurethane dispersion of the Dispercoll® U range combined with a superficially de-activated solid isocyanate like Dispercoll® BL XP 2514. Through the application of heat the isocyanate of the dried adhesive film is activated and crosslinking of the polymer takes place.

Waterbased adhesives Dispercoll® C
Dispercoll® C grades are waterbased polychloroprene dispersions which are formulated into sprayable adhesives. An aluminum salt spray solution is added to the spray mist during the application, which results in the coagulation of the adhesive film. The finished bonds show a good initial strength, fast crosslinking and a very good heat resistance. Typical applications are the bonding of foams for matresses and furniture upholstery.

Reactive polyurethane hotmelts with Baycoll®, Desmophen® and Desmodur®
Polyisocanates with suitable polyols are the raw materials for reactive polyurethane hotmelts for applications like general assembly processes or profiles and laminates for the furniture industry and similar uses. The finished adhesives are processed as a one-component system. They allow a high production efficiency and show an outstanding property profile. More on this here.

Ply-wood adhesives for engineered wood structures with Desmodur® E prepolymers
One-component adhesives based on Desmodur® E prepolymers are particularly suitable for the production of engineered wood structures. These plied wood layers (several layers of massive wood) play an important role in structural supports and wood frames, as they can carry an 80% higher load compared to the same structure made of massive wood. In addition to their technical and engineering advantages the are free of formaldehydes, too.
