Tetrasulfide Silane Coupling Agent Crosile®69 for Rubber
Bis-[γ-(triethoxysilyl)-propyl]-tetrasulfide Silane for Rubber
Chemical Properties
Silane coupling agent Crosile®69 Bis[3-(triethoxysilyl)propyl]tetrasulfide (TESPTS) is commonly used as a crosslinking agent and reinforcing filler in rubber manufacturing. TESPT Crosile®69 films provide corrosion protection to metal substrates. It is also used as a precursor for the synthesis of mesoporous silicones.
