Vinyltriethoxysilane is an organosilicon compound with the formula (C2H5O)3SiCH=CH2. It is a colorless liquid. The compound is bifunctional, featuring both a vinyl group and hydrolytically sensitive ethoxysilyl groups. As such it is a crosslinking agent.
==Applications== Vinyltriethoxysilane and the related vinyltrimethoxysilane are used as monomers and comonomer for polymers such as ethylene-vinyltrimethoxysilane and ethylene-vinyl acetate-vinyltrimethoxysilane. Vinyltrialkoxysilanes are also used as cross-linking agents during the manufacture of cross-linked polyethylene (PEX). The alkoxysilane moiety is reactive toward water, and in the presence of moisture, it forms silicon-oxygen-silicon bonds that cross-link the material to cure it. Moisture-curable polymers are used as electrical insulation in some kinds of cables and for water pipe in under-floor heating installations.
