Features Of Chem-Art SV6300 Silane Coupling Agent

  1. Highly reactive vinyl-functional silane for strong covalent bonding to inorganic substrates.

  2. Excellent hydrolytic stability in aqueous and solvent-based formulations.

  3. Enhances interfacial adhesion between silica fillers and organic polymer matrices.

  4. Low volatility and favorable handling safety profile compared to chlorosilane alternatives.

  5. Compatible with free-radical polymerization systems, including PVC, polyolefins, and unsaturated polyesters.

Typical Applications Of Chem-Art SV6300 Silane Coupling Agent

  1. Reinforced thermoset composites (e.g., fiberglass-reinforced polyester resins).

  2. High-performance rubber compounds for tires and industrial elastomers.

  3. Mineral-filled engineering plastics requiring improved tensile strength and impact resistance.

  4. Adhesives and sealants where durable bonding to glass, metal, or ceramic surfaces is critical.

  5. Surface treatment of fumed silica and precipitated silica for silicone rubber compounding.
