vinyltris2-methoxyethoxysilane Description

Vinyltris(2-methoxyethoxy)silane (CAS 1067-53-4) is a colorless to pale yellow, low viscosity liquid with a typical aromatic odor.

CAS 1067-53-4 silane is a vinyl-functional silane coupling agent that improves adhesion to a variety of organic polymers. It has reactive vinyl and hydrolyzable organosilanes whose reactive dual nature chemically binds to inorganic materials (e.g., glass, metals, fillers) and organic polymers (e.g., thermosets, thermoplastics, elastomers), thus acting as a crosslinker, adhesion promoter, and/or surface modifier.

UsesThis product is the coupling agent for filled rubber compound, and can also improve the durability of the emulsion and coatings. It enables a hydrophobic filler to improve the compatibility of the filler and polymer, and to achieve a better dispersion and lower melt viscosity. It can improve the bonding force between single fibers and resin, and improve the performance of composite materials in the wet state. It can provide crosslinking points for organic polymer. So it is used as polymer material modifier, EPDM rubber modifier, and cross-linking agent for cross-linking cable materials.

vinyltris2-methoxyethoxysilane: Guide

Vinyltris(2-methoxyethoxy)silane is a bifunctional molecule that reacts with inorganic fillers and organic polymers.It can be used as an adhesion promoter for a wide range of minerals: aluminum hydroxide, magnesium hydroxide, kaolin, silica and other filler polymers to improve their mechanical and electrical properties, especially after exposure to moisture. Better results.

Once bound to an inorganic filler, Vinyltris(2-methoxyethoxy)silane hydrophobizes the filler surface. This action improves the compatibility of the filler with the polymer, leading to better dispersion, lower melt viscosity and easier processing of the filled plastic.
