Product Description

Product Description

CFS-740 3-Mercaptopropyltrimethoxysilane  Cas No. 4420-74-0.

CFS-740, 3-Mercaptopropyltrimethoxysilane is a functional silane with a hydrolysable methoxy group and a reactive mercapto group. Its bifunctionality allows CFS-740 to promote the adhesion between organic materials and inorganic substrates. CFS-740 is mainly used in tires and silicone rubbers as a surface modifier and an adhesion promoter. It is the equivalent of Momentive Silquest A-189 or ShinEtsu KBM-803. It is also known as KH-590 in Chinese market.
