Organic Intermediate KH-580 / 3-Mercaptopropyltriethoxysilane Cas 14814-09-6
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.
