Vinyltrimethoxysilane (VTMO)

Vinyltrimethoxysilane is a functional organosilane coupling agent designed to enhance adhesion and compatibility between organic polymers and inorganic fillers or substrates. Its vinyl functional group allows participation in polymerization or crosslinking reactions, while the methoxy groups provide excellent surface reactivity and hydrolytic stability.

This silane is widely used in adhesives, sealants, coatings, and elastomers, as well as in composite materials, where improved mechanical properties, chemical resistance, and moisture durability are critical. It is especially effective for promoting bonding to glass, metal, and mineral surfaces.

Key Features:

• Enhances adhesion between organic and inorganic materials

• Compatible with a variety of polymers and resins

• Provides hydrolytic stability and chemical resistance

• Improves mechanical strength and durability in composites

Applications:

• Adhesives and sealants

• Coatings and paints

• Polymer composites

• Rubber and elastomer formulations
