Application
Bis(triethoxysilylpropyl)amine (CAS No. 13497-18-2), Silane coupling agent SCA-A67X, 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 SCA-A67X. It can react very fast with free isocyanate groups and lead to a high converted silane-endcapped product. Side reactions can be significantly reduced. SCA-A67X 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 SCA-A67X is that it does not contain traces of toxic aniline.
Examples of applications where SCA-A67X 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.
