3-Isocyanatopropyltrimethoxysilane

CAS Number
15396-00-6
EINECS
239-415-9

Description

Isocyanate functional silane. The isocyanate group reacts with hydroxyl and amine terminated polymers, which makes this the standard reagent for silane-modifying polyurethanes and polyethers into moisture-curable hybrid polymers. Also used directly as an adhesion promoter in PU systems. Releases methanol on hydrolysis.
