- (Triethoxysilyl)ethylene,Vinyltriethoxysilane
- Synonyms
- Vinyltriethoxysilane(Triethoxysilyl)ethylene
Surface Modification
Triethoxyvinylsilane is employed to alter the surface properties of materials. It can form covalent bonds with inorganic substrates and organic polymers, enhancing adhesion, hydrophobicity, or compatibility in composite materials.
Polymer Synthesis
This silane acts as a monomer or comonomer in the synthesis of silicone-based polymers and resins. It introduces vinyl functionality, enabling further crosslinking or functionalisation of the polymer chains.
Crosslinking Agent
It serves as an effective crosslinking agent in various polymer systems, such as silicone elastomers and coatings. The ethoxy groups hydrolyse to form silanol groups, which then condense to create a stable, three-dimensional network.
Adhesion Promoter
Used as an adhesion promoter, Triethoxyvinylsilane improves the bond strength between dissimilar materials, such as organic polymers and inorganic fillers or substrates in adhesives and coatings.
