Shin-Etsu KBM-1003 Silane Coupling Agent

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

Features Of Shin-Etsu KBM-1003 Silane Coupling Agent

  1. Dual Reactivity - Vinyl group bonds with polymers; methoxy group links to inorganic fillers

  2. Fast Hydrolysis - Methoxy groups enable quicker curing than ethoxy silanes

  3. Performance Enhancement - Boosts tensile strength, dielectric properties, and filler compatibility

  4. Multi-Matrix Adaptability - Compatible with PE, PP, EPDM, and thermosets

  5. Environmental Resistance - Improves wet-state stability in harsh conditions

Typical Applications Of Shin-Etsu KBM-1003 Silane Coupling Agent

  1. Wire & Cable - Crosslinked PE insulation for enhanced voltage resistance

  2. Composite Materials - Glass fiber/polyester interfaces in FRP

  3. Industrial Coatings - Adhesion promotion on metals/glass

  4. Ink Formulations - Pigment binding and substrate bonding

  5. Rubber Compounding - Filler treatment for EPDM/neoprene
