Shin-Etsu KBE-502 (3-methacryloxypropylmethyldiethoxysilane) is a dual-functional silane coupling agent that enhances interfacial adhesion between organic polymers (e.g., polyethylene, polypropylene) and inorganic fillers (e.g., silica). Its methacryloxy and ethoxy groups enable covalent bonding, improving mechanical strength, moisture resistance, and electrical properties in composites. Ideal for coatings, adhesives, and FRP, it offers fast curing at ambient temperatures while complying with REACH/RoHS standards
Hybrid Bonding - Methacryloxy links to polymers; ethoxy bonds with fillers/glass
Process Efficiency - Low viscosity (1.06 g/cm³) ensures easy mixing and application
Durability Boost - Enhances UV/chemical resistance in harsh environments
Multi-Matrix Compatibility - Effective with ABS, polycarbonate, and unsaturated polyester
Sustainable Solution - Halogen-free formulation for eco-sensitive application
Electronic Encapsulants - Moisture-resistant sealing for circuit components
Marine Coatings - Corrosion protection for metal substrates
Structural Adhesives - High-strength bonding in automotive/aerospace
FRP Reinforcement - Glass fiber treatment for mechanical strength
Industrial Inks - Durable printing on non-porous surfaces
