Description

Main Application:

As a hydrophobic silane coupling agent, it is used to fill silica in sol-gel or rubber systems (such as SBR/BR tire tread compounds), significantly reducing mixing viscosity, improving filler dispersion, enhancing the adhesion between inorganic fillers and the rubber matrix, reducing VOC emissions in finished tires, and improving aging resistance and dynamic mechanical properties.

Storage:

Keep tightly sealed and store in a dry, cool, well-ventilated area, avoiding contact with water or moisture (which causes slow hydrolysis). Recommended storage temperature: 2–8°C. Keep away from heat sources, open flames, and oxidizing agents. Use leak-proof containers and wear protective equipment during handling.
