Vinyl tris(2-methoxyethoxy) silane

Description

Vinyltris(2-methoxyethoxy)silane is a vinyl-functional coupling agent that promotes adhesion among unsaturated, polyester-type resins or crosslinked polyethylene resins or elastomers and inorganic substrates, including fiber glass, silica, silicates and many metal oxides. When used as coupling agent, it reduces the sensitivity of the products’ mechanical and electrical properties to heat and/or moisture.

Vinyl tris(2-methoxyethoxy) silane is mainly applied in these aspects:

1. As an efficient adhesion promoter for various mineral-filled polymers, improving mechanical and electrical properties especially after exposure to moisture.
2. A co-monomer for the preparation of different polymers such as polyethylene or acrylics. Those polymers show an improved adhesion to inorganic surfaces and they can also be crosslinked with moisture.
3. Improving the compatibility of fillers with polymers, leading to a better dispersibility, reduced melt viscosity and easier processing of filled plastics.
4. Pre-treating of glass, metals, or ceramic surfaces, improve the adhesion of coatings on these surfaces and corrosion resistance.
