γ-Mercaptopropyltrimethoxysilane

Silane USi-5301

Mercapto functional alkoxysilane

Product Description

Chemical Name:γ-Mercaptopropyltrimethoxysilane

CAS NO.: 4420-74-0

EINECS NO.: 224-588-5

Molecular Weight: 196.34

Properties

Silane USi-5301, has sulfhydryl-base function groups, and has special efficiency when as antirust of metal

surface. Disposing metal surface (gold, silver, copper) with it , can strengthen its surface to anti-corrupt, anti-oxidant and improve the sticking property between macromolecule ( resin) and it.

In rubber industry, usually used to deal with inorganic filling, such as whitecarbon black, carbon black, fiberglass,

mica, etc, can effectively improve mechanics performance and wear-resisting performance of the rubber. In the textile industry, can be used in the shrink proof finishing of the fabric.
