Name: Domestic KH580 LT580 Gamma-Mercaptopropyltriethoxysilane
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Domestic KH580 LT580 Gamma-Mercaptopropyltriethoxysilane

High-purity domestic alternative to imported gamma-mercaptopropyltriethoxysilane, meeting stringent quality consistency standards.
Reactive thiol (–SH) group enables strong covalent bonding with metals, fillers, and polymer matrices.
Hydrolyzable triethoxy silane functionality ensures robust siloxane network formation on inorganic surfaces.
Low volatility and excellent shelf stability under sealed, dry, cool storage conditions.
Compatible with common solvents (e.g., ethanol, isopropanol, toluene) for easy formulation integration.

Typical Applications Of Domestic KH580 LT580 Gamma-Mercaptopropyltriethoxysilane

Silane coupling agent for sulfur-cured rubber compounds (e.g., silica-reinforced tires and industrial rubber goods).
Surface modifier for metal oxides (e.g., ZnO, Fe₃O₄) in conductive or magnetic composites.
Adhesion promoter in epoxy, polyurethane, and silicone sealants for metal-to-polymer bonding.
Functionalization reagent for gold nanoparticles and biosensor substrates in diagnostic material science.
Interfacial compatibilizer in hybrid organic–inorganic coatings and anti-corrosion primers.
