Silane Coupling Agent Crosile970 3-Mercaptopropylmethyldimethoxysilane
3- Mercaptopropylmethyldimethoxysilane Crosile®970 has sulfhydryl-base function groups, and has special efficiency when as antirust of metal surface.
Disposing metal surface(for example, gold, silver, copper) with it, can strengthen its surface to anti-corrupt, anti-oxidant and improve the sticking property between macromolecule(for example, resin) and it.
Chemical Properties
3- Mercaptopropylmethyldimethoxysilane Crosile®970 is a colorless clear liquid with light typical odor. It is soluble in alcohols, ketones and aliphatic or aromatic hydrocarbons.
Silane Crosile®970 is a bifunctional organosilane possessing a reactive organic mercapto and a hydrolyzable inorganic methoxysilyl group.

Application
3- Mercaptopropylmethyldimethoxysilane Crosile®970 can be used as coupling agent to improve the adhesion of sulfur cured elastomers (polysulfide, polyurethane sealants) to inorganic fillers (such as silica, clay, glass, mica and talc etc.), fiberglass and surfaces.
Mineral-reinforced articles such as shoe soles, rubber rollers and wheels, white sidewalls, and wire and cable insulation also can be produced with lower silane loadings:
Used to improve properties of mineral filled elastomer, including modulus, tensile and tear strength, heat buildup, abrasion resistance, resilience, compression set and cure time.
Used as a pretreatment on minerals or added at the time of compounding.
Used to improve low-rolling resistance in silica-reinforced tire tread compounds.
