Chemical Characteristics
It is a bifunctional silane coupling agent containing triethoxysilyl group and disulfide group. The ethoxy group can hydrolyze and bond with hydroxyl groups on inorganic fillers; the disulfide group can react chemically with rubber molecular chains during vulcanization, forming stable chemical bonding between inorganic filler and rubber matrix.

Safety Information Of
Product Application Of
- Rubber Reinforcement & CompoundingMainly used in tire rubber, conveyor belt, rubber hose and rubber shoe industry. It significantly improves the bonding force between silica, carbon black and rubber, enhances tensile strength, wear resistance and tear resistance.
- Low Rolling Resistance Tire FormulaApplied in green tire formula with silica filler; reduces rolling resistance, saves fuel consumption, improves wet skid resistance and driving safety.
- Inorganic Filler Surface ModificationSurface treatment agent for silica, talc, clay and calcium carbonate; improves dispersion of fillers in rubber and plastics, reduces compound viscosity and increases filling amount.
- Adhesion PromotionEnhances adhesion between rubber and metal, glass, fiber and other substrates; suitable for rubber-metal composite products.
- Engineering Plastics ModifiedUsed as compatibilizer and coupling agent for modified plastics filled with inorganic powder, improving mechanical properties, heat resistance and dimensional stability.
- Sealant & Coating AdditiveUsed in special rubber sealants and anti-corrosion coatings to enhance filler dispersion, waterproof performance and aging resistance.
