Bis(trimethoxysilylpropyl)amine (CAS No. 82985-35-1), Silane coupling agent NQ-351, 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 NQ-351. It can react very fast with free isocyanate groups and lead to a high converted silane-endcapped product. Side reactions can be significantly reduced.
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.
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.
