Product Description

Chemical Name:

γ-Mercaptopropyltrimethoxysilane 

CAS NO.:   4420-74-0

EINECS NO.:   224-588-5   

Properties

Silane OSi HIOSil MTMO, 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 white carbon 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.
