3-Mercaptopropyltriethoxysilane (Mercapto Silane Oligomer)

Features

1. Mercapto Silane Oligomer is prepared by the hydrolysis-condensation reaction of 3-Mercaptopropyltriethoxysilane (KH580 Mercaptosilane).  It substitute of Momentive T-Cure. Compared to monomeric silanes, its oligomeric form results in a more uniform film, longer storage time, and higher stability.

2. It features a high content of mercapto and triethoxy functional groups, enabling the formation of strong chemical bonds between inorganic materials (e.g., glass, metals, fillers) and organic polymers (e.g., rubber, resins). This significantly enhances the adhesion, mechanical properties, and durability of composites.

Applications

• Metal surface treatment — Treating metal surfaces such as gold, silver, and copper improves corrosion resistance, oxidation resistance, and adhesion to polymeric materials.

• Coatings — Enhances adhesion between primers and various substrates (e.g., metal, glass, plastic) while also improving interlayer adhesion between topcoats and primers, effectively preventing coating delamination.
