Vinyltrimethoxysilane, 98%

Description

CAS: 2768-02-7 | C5H12O3Si | 148.23 g/mol

Trimethoxyvinylsilane is used as a chemical intermediate in the production of other fine chemicals or as a monomer in the production of vinyl functional silicone polymers. The use of Trimethoxyvinylsilane in coatings is intended to improve bonding or adhesion between organic polymers and mineral surfaces, such as pigments, fillers, and glass or metal substrates. It is used in water-based decorative coating products. It is also used as a as cross-linking agent and adhesion promoter in commercially-available silicone sealant product.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
