Properties
Silane-terminated polyurethanes can be prepared by reacting traditional NCO-terminated urethane prepolymers. It can reactvery fast with freeisocyanate 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.
