Properties: Colorless transparent liquid, soluble in a variety of organic solvents. It is a bifunctional organosilane possessing a reactive organic mercapto and a hydrolysable inorganic methoxysilyl group. The dual nature of its reactivity allows it to bind chemically to both inorganic materials (e.g. glass, metals, fillers) and organic polymers (e.g. thermoplastics, thermosets or elastomers) thus functioning as adhesion promoter, crosslinker agent, surface modifier or reactive reagent.
It is a clear, colorless liquid with a slightly mercaptan odor. It is soluble in alcohols, ketones and aliphatic or aromatic hydrocarbons.

Application:

YCS189 silane coupling agent has sulfhydryl-base function groups, and is specially effective when used as metal surface rust inhibitor. Processing metal surface such as gold, silver, copper etc. with it can enhance the surface corrosion resistance, oxidation resistance and to increase the adhesion with resins and other polymer.
In the rubber industry, YCS189 is usually used to process white carbon black, carbon black, glass fibers, mica, and other inorganic fillers. YCS189 can effectively improve the mechanical properties and wear-resistance of the rubber.
In the textile industry, YCS189 can be used in the shrink-proof finishing of the fabric.
Package and Storage: 5L, 10L, 25L, 200L PE drum or 1000L IBC container.must be sealed and kept in cool and ventilated place, away from water, heat and fire.
