Shin-Etsu KBE-703 (γ-Chloropropyltriethoxysilane) is a specialized silane coupling agent designed to enhance interfacial adhesion between halogenated rubbers and inorganic fillers. This colorless liquid improves mechanical properties through covalent bonding with silanol-containing substrates while maintaining compatibility with organic matrices. Its controlled hydrolysis characteristics ensure stable processing in rubber compounding and coating systems
Halogen-Rich Compatibility - Optimized for chloroprene, chlorosulfonated polyethylene, and other halogenated rubbers
Dual Reactivity - Ethoxy groups for inorganic bonding; chloropropyl for organic phase coupling
Mechanical Reinforcement - Enhances tensile strength and filler dispersion in composites
Hydrolysis Stability - Controlled reactivity with moisture for consistent performance
Multi-Industry Adaptability - Effective in coatings, adhesives, and rubber processing
Rubber Compounding - Coupling agent for silica-filled halogenated rubber
Anti-Corrosion Coatings - Adhesion promoter for metal substrates
Composite Materials - Surface treatment for glass fiber reinforcements
Sealant Formulations - Crosslinking agent in polysulfide sealants
Ink Additives - Enhances pigment binding in specialty inks
