SiSiB is worldwide leading manufacturer of organosilanes for over 30 years. SiSiB mercapto silanes are functional organosilanes with sulfhydryl functional group. They are formulated with a hydrolysable alkoxy group and a reactive mercapto group. With the presence of mercapto group and alkoxy group, mercapto silanes are mainly used as adhesion promoter, surface modifier, coupling agent and crosslinker in a wide variety of application.
Mercapto silanes by SiSiB silicone factory often are used to deal with silica, carbon black and other inorganic filler. They play an active agent, coupling agent, crosslinking agent in rubber and silicone rubber polymer.
Several mercapto silanes are available at SiSiB. SiSiB® PC2300 (3-Mercaptopropyltrimethoxysilane) is the most popular with the biggest consumption. In addition, SiSiB also offers other mercapto silanes, such as SiSiB® PC2310 (3-Mercaptopropyltriethoxysilane) and SiSiB® PC2320 (3-Mercaptopropylmethyldimethoxysilane).
SiSiB mercapto silanes are widely used in rubber industry and tires industry with special effect. They can make rubber, fumed silica and other inorganic fillers to produce excellent coupling effect. They can significantly improve the physical and mechanical properties of products, especially suitable for sulfur vulcanization and peroxide vulcanization system. SiSiB mercapto silanes can improve the tensile strength of rubber, reduce its permanent compression deformation and improve the wear resistance of rubber.
Besides increasing the consumption of inorganic fillers, SiSiB mercapto silanes can improve overall performances of composites. Specifically, SiSiB mercapto silanes can improve mechanical and electrical properties of compounds; enhance the moisture resistance, corrosion resistance and thermal resistance. SiSiB mercapto silanes are capable of reducing the interactions more efficiently in UV cure systems.
