Shin-Etsu KBM-1003 (Vinyltrimethoxysilane) is a reactive silane coupling agent that enhances interfacial adhesion between organic polymers (e.g., polyethylene, unsaturated polyester) and inorganic substrates (e.g., glass fibers, metals). Its dual-functional vinyl/methoxy groups enable covalent bonding, improving mechanical strength, moisture resistance, and electrical properties in composites. Ideal for coatings, inks, and cable insulation, it offers fast hydrolysis and excellent filler dispersion
Dual Reactivity - Vinyl group bonds with polymers; methoxy group links to inorganic fillers
Fast Hydrolysis - Methoxy groups enable quicker curing than ethoxy silanes
Performance Enhancement - Boosts tensile strength, dielectric properties, and filler compatibility
Multi-Matrix Adaptability - Compatible with PE, PP, EPDM, and thermosets
Environmental Resistance - Improves wet-state stability in harsh conditions
Wire & Cable - Crosslinked PE insulation for enhanced voltage resistance
Composite Materials - Glass fiber/polyester interfaces in FRP
Industrial Coatings - Adhesion promotion on metals/glass
Ink Formulations - Pigment binding and substrate bonding
Rubber Compounding - Filler treatment for EPDM/neoprene
