Shin-Etsu KBE-502 Silane Coupling Agent

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

Features Of Shin-Etsu KBE-502 Silane Coupling Agent

  1. Hybrid Bonding - Methacryloxy links to polymers; ethoxy bonds with fillers/glass

  2. Process Efficiency - Low viscosity (1.06 g/cm³) ensures easy mixing and application

  3. Durability Boost - Enhances UV/chemical resistance in harsh environments

  4. Multi-Matrix Compatibility - Effective with ABS, polycarbonate, and unsaturated polyester

  5. Sustainable Solution - Halogen-free formulation for eco-sensitive application

Typical Applications Of Shin-Etsu KBE-502 Silane Coupling Agent

  1. Electronic Encapsulants - Moisture-resistant sealing for circuit components

  2. Marine Coatings - Corrosion protection for metal substrates

  3. Structural Adhesives - High-strength bonding in automotive/aerospace

  4. FRP Reinforcement - Glass fiber treatment for mechanical strength

  5. Industrial Inks - Durable printing on non-porous surfaces
