Bis[3-(triethoxysilyl)propyl]disulfide (Si-75)

Bis[3-(triethoxysilyl)propyl]disulfide (Si-75) is a sulfur-containing silane used as a coupling agent and adhesion promoter. It significantly improves the bond strength between rubber and inorganic substrates, making it ideal for applications in the automotive and construction industries. This product also acts as a crosslinker, enhancing the mechanical properties of rubber compounds. Notable for its ability to improve wet grip and reduce rolling resistance, Si-75 is a key component in high-performance tire manufacturing.
