Application
3- Mercaptopropylmethyldimethoxysilane Censil 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.
3- Mercaptopropylmethyldimethoxysilane Censil 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.
In rubber industry, usually used to deal with inorganic filling, such as white carbon black, carbon black, fiberglass, mica, etc, can effectively improve mechanics performance and wear-resisting performance of the rubber.
In the textile industry, can be used in the shrinkproof finishing of the fabric.
Improves the adhesion of polysulfide and polyurethane sealants to glass and metal surfaces. Improves low-rolling resistance in silica-reinforced tiretread compounds. Enhances properties in mineral-reinforced articlessuch as shoe soles, rubber goods.
