DOWSIL Z-6011 (γ-aminopropyltriethoxysilane) is a high-purity (≥98.5%) amino-functional silane coupling agent that enhances adhesion between organic polymers (epoxy, polyurethane) and inorganic substrates (glass, metals). Its dual-reactive groups improve wet/dry strength (>50% increase) and transparency in composites. With low viscosity (1.6 cSt) and 18kg/190kg packaging options, it's ideal for FRP, adhesives, and coatings, complying with REACH/RoHS standards
Dual Reactivity - Amino groups bond with resins; ethoxy links to fillers/glass fibers for optimized stress transfer .
Performance Boost - Enhances wet-state flexural strength (100% increase) and composite transparency .
Process Adaptability - Self-emulsifying in water (pH 3.0–4.5) or soluble in alcohols (e.g., ethanol) .
Durability - Improves thermal stability (up to 200°C) and chemical resistance in harsh environments .
FRP Composites - Glass fiber sizing for automotive/construction (50% strength increase) .
Adhesives/Sealants - Enhances epoxy/polyurethane bonding to metals (Al, steel) and glass .
Rubber Reinforcement - Mineral-filled EPDM/NBR with improved mechanical properties .
Coatings - Waterborne systems with superior adhesio
