CAS # 14814-09-6

Application Information

• Mercapto-functional Coupling agent in polysulfide and polyurethane caulks & sealants
• Used in sulfur-cured and metal oxide-cured elastomers; Can be added at time of compounding or used to pretreat minerals beforehand
• Chemically bonding reinforcing minerals like silica, clay, mica, and talc to the polymer matrix; Properties including modulus, tensile and tear strength, heat buildup, abrasion resistance, reslience, compression set and cure time are improved in mineral filled elastomers.

Description：
3-Mercaptopropyltriethoxysilane is a silane coupling agent containing a hydrolysable ethoxy group and a reactive mercapto group. It is mainly used in tires and silicone rubbers as a surface modifier and an adhesion promoter.

It is known as KH-580 in China and normally acts as the counterpart of Momentive Silquest A-1891 or ShinEtsu KBE-803.
