Product Description

Chemical Name:  Vinyltrimethoxysilane

Synonym:   (Trimethoxysilyl)ethylene;

              Ethenyltrimethoxysilane;

              Trimethoxy(vinyl)silane

CAS NO.:  2768-02-7

EINECS NO.:  220-449-8

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 also

have 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.
