Chenguang KH-590 Silane Coupling Agent

Chenguang KH-590 (γ-mercaptopropyltrimethoxysilane) is a dual-functional coupling agent that enhances interfacial bonding between polymers (rubber, epoxy) and inorganic substrates (glass fibers, metals). Its reactive thiol and methoxy groups improve wet adhesion (>90% retention), mechanical strength, and chemical resistance in composites. Ideal for tires, cables, and coatings, it enables fast curing at ambient temperatures and complies with REACH/RoHS, reducing VOC emissions by 15–20%

Features Of Chenguang KH-590 Silane Coupling Agent

  1. Dual Reactivity - Thiol groups bond with sulfur-cured rubbers; methoxy links to fillers/fibers, optimizing stress transfer

  2. Process Efficiency - Lowers viscosity (1.050–1.060 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 NR, EPDM, SBR, and polyurethan

Typical Applications Of Chenguang KH-590 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
