Chenguang KH-560 (γ-glycidoxypropyltrimethoxysilane) is an epoxy-functional silane coupling agent that enhances interfacial bonding between resins (epoxy, acrylic) and inorganic substrates (glass fibers, metals). It improves wet adhesion (>90% retention), mechanical strength, and electrical properties in composites through siloxane crosslinking. Ideal for FRP, coatings, and electronics, it enables fast curing at ambient temperatures and complies with REACH/RoHS, reducing VOC emissions by 15–20%
Interfacial Reinforcement - Epoxy groups bond with resins; methoxy links to fillers/fibers, optimizing stress transfer .
Process Efficiency - Lowers viscosity (1.065–1.075 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, polyurethane, and nylon resins
FRP Composites - Glass fiber sizing for automotive parts (30% strength increase) .
Electronics - Epoxy-based sealants with improved dielectric properties .
Industrial Coatings - Metal primers with enhanced corrosion resistance
Adhesives - Polysulfide/polyurethane formulations for aerospace .
