DOWSIL Z-6030 Silicate Coupling Agent

DOWSIL Z-6030 (γ-methacryloxypropyltrimethoxysilane) is a bifunctional silane coupling agent that enhances adhesion between organic resins (e.g., polyester, acrylic) and inorganic substrates (glass, quartz). Its low viscosity (2.5 cSt) and dual reactivity (methacrylate + methoxy) improve wet/dry strength (>100% increase) and chemical resistance in composites. Complies with REACH/RoHS, ideal for FRP, coatings, and cable insulation

Features Of DOWSIL Z-6030 Silicate Coupling Agent

  1. Interfacial Bonding - Methacrylate groups copolymerize with resins; methoxy links to fillers/glass fibers

  2. Performance Boost - Enhances wet-state flexural strength and transparency in polyester composites

  3. Process Adaptability - Soluble in water (hydrolyzed) or organic solvents (e.g., n-butanol)

Typical Applications Of DOWSIL Z-6030 Silicate Coupling Agent

  1. Metal/Glass Coatings - Primer for automotive/architectural surfaces

  2. FRP Composites - Glass fiber sizing (30% strength increase)

  3. Cable Insulation - Clay-filled EPDM dielectric enhancement
