Shin-Etsu KBE-9007 (3-isocyanatopropyltriethoxysilane) is an isocyanate-functional silane coupling agent that enhances adhesion between organic polymers (e.g., polyurethane, epoxy) and inorganic substrates (e.g., metals, glass). It forms covalent bonds via its isocyanate and ethoxy groups, improving mechanical strength, chemical resistance, and moisture protection in coatings and adhesives. Compatible with solvent/water-based systems, it cures rapidly at ambient temperatures and complies with REACH standards
Dual Reactivity - Isocyanate bonds with resins; ethoxy links to metals/glass
Hydrolysis Stability - Moisture-resistant curing without yellowing
Broad Compatibility - Effective with PU, epoxy, and acrylic resins
Process Efficiency - Low viscosity (0.999 g/mL) for easy integration
Durability Boost - Enhances UV/chemical resistance in harsh environment
Anti-Corrosion Coatings - Long-term protection for steel structures
Industrial Coatings - Wear/chemical resistance for machinery
Architectural Coatings - Weather-resistant finishes for facades
Electronic Encapsulation - Moisture-proof sealing for PCBs
Adhesive Formulations - High-strength bonding in automotive/aerospace
