Isocyanatomethyldimethoxysilane

CAS Number
406679-89-8

Description

Isocyanate functional silane. The isocyanate group sits on a short methylene bridge to silicon rather than the more common propyl spacer, and the silicon carries a methyl plus two methoxy groups — a difunctional grade used mainly to build and modify MS polymer (silane-terminated polyether) backbones.
