Application 3-(CYCLOHEXYLAMINO)PROPYLTRIMETHOXYSILANE(CAS No.3068-78-8), Silane coupling agent KH-557, is a bifunctional secondary amino-functional silane. It is an important additive for many applications. Examples are: Silane-endcapped Polyurethanes: Silane-terminated polyurethanes can be prepared by reacting traditional NCO-terminated urethane prepolymers with KH-557. It can react very fast with free isocyanate groups and lead to a high converted silane-endcapped product. Side reactions can be significantly reduced. KH-557 is the most recommended silane for endcapping Polyurethanes. It leads to colorless low-viscosity PU prepolymers with improved UV stability and reduced yellowing tendency of sealants. Another benefit of KH-557 is that it does not contain traces of toxic aniline. Examples of applications where KH-557 used include polyurethanes for structural adhesives, parquet adhesives and over-paintable hybrid sealant. Glass fiber/glass fabric composites: As a finish or size constituent Mineral fiber insulating materials and abrasives: As an additive to phenolic resin binders Foundry resins: As an additive to phenolic, furan and melamine resins Sealants and adhesives: As a primer or additive and for chemical modification Mineral-filled polymers (composites) or HFFR cables: For pretreatment of fillers and pigments Paints and coatings: As an additive and primer for improving adhesion to the substrate. As a primer for glass and metal.
