Name: Domestic KH151 LT151 Vinyltriethoxysilane
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Domestic KH151 LT151 Vinyltriethoxysilane

High-purity vinyl-functional silane with excellent hydrolytic stability under controlled conditions.
Reactive vinyl group enables covalent bonding with unsaturated polymers (e.g., SBR, EPDM) during vulcanization or curing.
Three ethoxy groups provide efficient condensation reactivity with inorganic surfaces such as glass, silica, and metal oxides.
Low volatility and favorable handling characteristics compared to methoxy-substituted analogues.
Compatible with common organic solvents and widely used in solvent-based and low-VOC formulation systems.

Typical Applications Of Domestic KH151 LT151 Vinyltriethoxysilane

Adhesion promoter in rubber-to-metal bonding for automotive components (e.g., brake hoses, engine mounts).
Surface modifier for silica-reinforced elastomers to enhance filler dispersion and tensile strength.
Bridge coupling agent in hybrid organic-inorganic coatings and sealants.
Functional additive in glass fiber sizing formulations to improve resin compatibility and composite interfacial strength.
Co-monomer in sol-gel synthesis of vinyl-functionalized silica hybrids for specialty coatings.
