Sulfur Silanes

CG-580 (3-(triethoxysilyl)propanethiol) is commonly used to treat inorganic fillers such as SiO2 and carbon black. It functions as an activator, coupling agent, crosslinking agent, and reinforcing agent in polymers like rubber and silicone rubber. It can also be used as a curing agent and UV initiator for epoxy resin.

CG-590 (3-trimethoxysilylpropane-1-thiol) is a silane coupling agent with mercapto functional groups, used for treating metal surfaces such as gold, silver, and copper to improve corrosion resistance, oxidation resistance, and enhance adhesion to polymeric materials.

CG-Si50 (Mixture of CG-Si69 and carbon black) provides the same functionality as CG-Si69 while offering easier handling. As a rubber and tire additive, it improves the physical and mechanical properties of rubber, enhancing tensile strength, tear strength, and wear resistance while reducing permanent deformation. Additionally, it reduces compound viscosity and improves processing performance.

CG-Si69 (Bis[3-(triethoxysilyl)propyl]tetrasulfide) is a multifunctional organosilicone rubber and tire additive successfully applied in the rubber industry. It improves the elastic modulus and tensile strength of rubber, significantly enhances wear resistance and compression performance, while reducing rubber viscosity and saving processing energy.

CG-Si75 (Bis(triethoxysilylpropyl) disulfide) is a multifunctional silane coupling agent and tire additive successfully applied in the rubber industry. It improves the elastic modulus and tensile strength of rubber, significantly enhances wear resistance and compression performance, while reducing rubber viscosity and saving processing energy.

CG-Si264 (Triethoxy(3-thiocyanatopropyl)silane) is a sulfur-containing silane primarily used in silicone rubber and rubber applications. When used with fillers in the rubber industry, it differs from CG-Si69 by improving the anti-reversion properties of natural rubber, enhancing stability, and reducing scorching. Due to its light color, it is suitable for light-colored rubber products such as white rubber shoe soles.

CG-Si698 (S-(3-triethoxysilylpropyl) octanethioate) is used in silica-filled tread compounds to reduce compound viscosity, decrease mixing stages, improve processing performance and dispersibility, enhance aging resistance and dynamic mechanical properties of vulcanized rubber, extend storage time, and reduce volatile organic compound content in finished tires.
