Vinyltrimethoxysilane

Silane USi-401

Vinyl functional alkoxysilane

Product Description

Chemical Name: Vinyltrimethoxysilane

Synonym: (Trimethoxysilyl)ethylene;Ethenyltrimethoxysilane;Trimethoxy(vinyl)silane

CAS NO.: 2768-02-7

EINECS NO.: 220-449-8

Molecular weight：148.23

Properties

Pipes and cables produced from silane-crosslinked polyethylene (PE-Xb) using USi-401 are more resistant to heat and weathering than products made from non-crosslinked polyethylene. They alsohave improved electrical properties. The storage stability is greatly enhanced in formulations of silane crosslinking adhesives and sealants.

Use of USi-401 as a co-monomer in polymer dispersions results in binders which exhibit much improved wet scrub resistance and higher abrasion resistance thanks to crosslinking and improved adhesion to the substrate.
