Name: Shin-Etsu KBM-1003 Vinyltrimethoxysilane
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Shin-Etsu KBM-1003 Vinyltrimethoxysilane

High-purity vinyl-functional silane with excellent hydrolytic stability under controlled conditions.
Reactive vinyl group enables covalent bonding with organic polymers (e.g., polyethylene, EVA) via free-radical grafting.
Three methoxy groups provide strong condensation reactivity with inorganic surfaces (glass, silica, metals) for durable interfacial adhesion.
Low volatility and favorable handling characteristics compared to chlorosilane alternatives.
Consistent batch-to-batch performance validated through rigorous QC testing per Shin-Etsu’s global manufacturing standards.

Typical Applications Of Shin-Etsu KBM-1003 Vinyltrimethoxysilane

Adhesion promoter in silicone rubber compounds for improved bonding to metal and plastic substrates.
Grafting agent for polyolefin-based cable insulation and automotive sheathing materials.
Surface modifier for silica fillers in high-performance RTV and HTV silicone elastomers.
Key coupling component in glass fiber-reinforced thermoplastics (e.g., PA6, PBT) to enhance mechanical strength and moisture resistance.
