Reactive silane coupling agent with dual functionality: methoxy groups for hydrolytic reactivity and vinyl groups for radical polymerization compatibility.
Enables strong covalent bonding between inorganic substrates (e.g., glass, silica, metals) and organic polymers.
Improves dispersion stability and interfacial adhesion in filled composites and coatings without requiring harsh catalysts.
Low volatility and hydrolytic stability in anhydrous formulations, supporting extended shelf life and safe handling.
Compatible with common industrial processes including solvent-based coating, extrusion compounding, and RTV silicone formulation.
Adhesion promoters in automotive OEM and refinish coatings for metal and composite substrates.
Surface treatment of silica and glass fillers in high-performance rubber and thermoplastic composites.
Functional additive in RTV-2 silicone elastomers to enhance filler-matrix interaction and mechanical durability.
Primer component for optical lenses, LED encapsulants, and electronic potting compounds requiring long-term environmental resistance.
Performance enhancer in waterborne and UV-curable industrial coatings for improved scratch resistance and substrate wetting.
