Properties

Silane OSi HIOSil 1124 is an essential additive in the

below industry:

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.
