Chenguang KH-550 Silane Coupling Agent

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%

Features Of Chenguang KH-550 Silane Coupling Agent

  1. Dual Reactivity - Amino groups bond with resins; ethoxy links to fillers/fibers, optimizing stress transfer

  2. Process Efficiency - Lowers viscosity (0.938–0.945 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 epoxy, polyamide, and phenolic resins

Typical Applications Of Chenguang KH-550 Silane Coupling Agent

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

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

  3. Metal Primers - Adhesion promotion for aluminum/steel in industrial coatings

  4. Adhesives - Epoxy/polyurethane formulations with 0-level adhesion (ASTM D3359
