Dow Corning OFS-6030 (γ-methacryloxypropyltrimethoxysilane) is a bifunctional silane coupling agent that enhances adhesion between organic resins (polyester, acrylic) and inorganic substrates (glass fibers, metals). It forms durable siloxane crosslinks, improving wet adhesion (>90% retention) and mechanical strength in composites. Ideal for FRP, coatings, and cables, it complies with REACH/RoHS and enables fast curing at ambient temperatures
Interfacial Reinforcement - Methacryloxy groups copolymerize with resins; methoxy links to fillers/fibers, optimizing stress transfer
Process Efficiency - Lowers viscosity (1.040–1.053 g/cm³) for homogeneous filler dispersion
Durability - Enhances UV/aging resistance in coatings (salt spray resistance >1,000 hours)
Multi-Matrix Compatibility - Works with polyester, epoxy, and polyurethane resins
FRP Composites - Glass fiber sizing for automotive parts (30–50% strength increase)
Wire Insulation - Crosslinked polyethylene cables with improved dielectric properties
Industrial Coatings - Metal primers with enhanced corrosion resistance
Adhesives - Acrylic formulations with 0-level adhesion (ASTM D3359)
