Polyisocyanates and polyoles for the production of two-component polyurethane adhesive and sealant systems
Bayer MaterialScience is the market leader of polyisocyanates und polyoles for the production of one- and two-component polyurethane systems. The product range is the most comprehensive in the market and covers a vast number of applications. Among the product types are polyisocyanate crosslinkers, hydrophilic and blocked polyisocyanates and polyisocanates for water reduceable or high solid systems and many more. By specific combinations of appropriate polyisocyantes with polyoles and proper formulation the adhesive end products can be fine-tuned to obtain specific properties or to suit specific processing conditions.
In general, adhesives and sealants based on aromatic polyisocyanates can be characterized by an excellent mechanical and chemical resistance. Aliphatic polyisocyanates offer the additional advantage of lightfastness. Many of these systems are used for bondings and sealants in the automotive industry (OEM and refinish), in the footwear industry, in the furniture industry (e.g. 3D-lamination) or for parquet/hardwood floor adhesives, just to name a few. Please discuss your requirements regarding formulations and properties with our specialists.
