4. Use of Bis[3-(triethoxysilyl)propyl]amine
Bis(triethoxysilylpropyl)amine, is an important additive for many applications. Silane-terminated polyurethanes can be prepared by reacting traditional NCO-terminated urethane prepolymers with KH-1171. 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-1171 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-1171 is that it does not contain traces of toxic aniline.
