Chenguang KH-570 Silane Coupling Agent

Chenguang KH-570 (γ-methacryloxypropyltrimethoxysilane) is a dual-functional silane coupling agent that enhances interfacial bonding between resins (acrylic, epoxy) and inorganic substrates (glass fibers, metals). It improves wet adhesion (>90% retention), mechanical strength, and chemical resistance in composites through siloxane crosslinking. Ideal for FRP, cables, and coatings, it enables fast curing at ambient temperatures and complies with REACH/RoHS, reducing VOC emissions by 20%

Features Of Chenguang KH-570 Silane Coupling Agent

  1. Interfacial Reinforcement - Methacryloxy groups copolymerize with resins; methoxy links to fillers/fibers, optimizing stress transfer

  2. Process Efficiency - Lowers viscosity (1.040–1.053 g/cm³) for homogeneous filler dispersion

  3. Durability - Enhances UV/aging resistance in coatings (salt spray resistance >1,000 hours)

  4. Multi-Matrix Compatibility - Works with acrylic, epoxy, and polyurethane resins

Typical Applications Of Chenguang KH-570 Silane Coupling Agent

  1. FRP Composites - Glass fiber sizing for automotive parts (30–50% strength increase)

  2. Wire Insulation - Crosslinked polyethylene cables with improved dielectric properties

  3. Industrial Coatings - Metal primers with enhanced corrosion resistance

  4. Adhesives - Acrylic formulations with 0-level adhesion (ASTM D3359
