Vinyltriethoxysilane (VTEO)

Vinyltriethoxysilane is a functional organosilane coupling agent used to improve adhesion and compatibility between organic polymers and inorganic fillers or substrates. The vinyl functional group enables participation in polymerization or crosslinking reactions, while the ethoxy groups provide excellent surface reactivity and hydrolytic stability.

This silane is commonly applied in adhesives, sealants, coatings, and elastomers, as well as in composite materials, where enhanced mechanical properties, chemical resistance, and moisture durability are desired. It is particularly effective for bonding to glass, metals, and mineral surfaces.

Key Features:

• Promotes adhesion between organic and inorganic materials

• Compatible with a wide range of polymers and resins

• Provides hydrolytic stability and chemical resistance

• Enhances mechanical strength and durability in composites

Applications:

• Adhesives and sealants

• Coatings and paints

• Polymer composites

• Rubber and elastomer formulations
