Chenguang KH-550 (γ-aminopropyltriethoxysilane) is a bifunctional silane coupling agent that strengthens adhesion between organic resins (epoxy, polyurethane) and inorganic substrates (glass, metals). It enhances wet-state mechanical strength (>90% retention) and chemical resistance in composites via siloxane crosslinking. Ideal for FRP, coatings, and adhesives, it enables fast curing at ambient temperatures and complies with REACH/RoHS, reducing VOC emissions by 15–20%
Dual Reactivity - Amino groups bond with resins; ethoxy links to fillers/fibers, optimizing stress transfer
Process Efficiency - Lowers viscosity (0.938–0.945 g/cm³) for homogeneous filler dispersion
Durability - Enhances UV/aging resistance in coatings (salt spray resistance >1,000 hours) .
Multi-Matrix Compatibility - Works with epoxy, polyamide, and phenolic resins
FRP Composites - Glass fiber sizing for automotive parts (30% strength increase)
Wire Insulation - Crosslinked polyethylene cables with improved dielectric properties
Metal Primers - Adhesion promotion for aluminum/steel in industrial coatings
Adhesives - Epoxy/polyurethane formulations with 0-level adhesion (ASTM D3359
