AC-AL25

3-Isocyanatopropyltriethoxysilane

CAS Number
24801-88-5
EINECS
246-467-6

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 ethanol on hydrolysis.
