OSi HIOSil MTMO CAS 4420-74-0

Product Description

Chemical Name: γ-Mercaptopropyltrimethoxysilane 

CAS NO.: 4420-74-0

EINECS NO.: 224-588-5   

Chemical structure: 

Properties

Silane OSi HIOSil MTMO, has sulfhydryl-base function groups, and has special efficiency when used as an antirust of the metal surface. Disposing metal surfaces (gold, silver, copper) with it can strengthen its surface to be anti-corrupt, and anti-oxidant and improve the sticking property between the macromolecule (resin) and it. 

In the rubber industry, it's usually used to deal with inorganic filling, such as white carbon black, carbon black, fiberglass, mica, etc., which can effectively improve the mechanics performance and wear-resisting performance of the rubber. In the textile industry, it can be used in the shrink-proof finishing of the fabric.
