CFS 740 3 Mercaptopropyltrimethoxysilane A 189/MTMO/KH 590 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.

CFS-740 is soluble in various solvents. It can be used as a primer in coatings and adhesives industries.
CFS-740 can improve mechanical and electrical properties of silicone rubbers and tires.
CFS-740 can be used as an adhesion promoter and fillers/pigments modifier in coating and sealants industries.
CFS-740 can be used as a surface modifier and an adhesion promoter to prepare silylation surface treatment agents of metal. Other suitable inorganic substrates are glass, silica and kaolin.
