DOWSIL Z-6040 (γ-glycidoxypropyltrimethoxysilane) is a dual-functional epoxy silane coupling agent that enhances adhesion between organic resins (epoxy, polyurethane) and inorganic substrates (glass, metals). Its reactive epoxy and methoxy groups form covalent bonds, improving wet/dry strength (>30% increase) and chemical resistance. Ideal for FRP, coatings, and adhesives, it complies with REACH/RoHS and offers low viscosity (1.6 cSt) for easy processing
Interfacial Bonding - Epoxy groups react with resins; methoxy links to glass/metals for stress transfer
Performance Boost - Enhances wet-state strength retention in composites and coatings
Process Adaptability - Soluble in water (hydrolyzed) or organic solvents (e.g., n-butanol)
Metal/Glass Coatings - Primer for automotive/architectural surfaces
FRP Composites - Glass fiber sizing (30% strength increase)
Cable Insulation - Clay-filled EPDM dielectric enhancement
