Product Description
Abstract
3-Mercaptopropyltrimethoxysilane (CAS No. 4420-74-0), silane coupling agent SCA-S89M, is a versatile mercapto functional silane suitable to promote the adhesion between fillers such as silica and sulfur crosslinked rubber such as NR, SBR, BR, EPDM and etc.

Application
3-Mercaptopropyltrimethoxysilane (CAS No. 4420-74-0), silane coupling agent SCA-S89M, can improve the properties of the mineral-filled elastomer, including modulus, tensile and tear strength, heat buildup, abrasion resistance, resilience, compression set and cure time may be achieved with SCA-S89M. This silane chemically bonds reinforcing minerals such as silica, clay, mica and talc to the polymer matrix especially the sulfur-cured and metal oxide-cured rubber and elastomer. It can be used as a pretreatment on minerals or added at the time of compounding. Mineral-reinforced rubbers such as shoe soles, rollers, wheels, white sidewalls, wire and cable insulation are the common case SCA-S89E could be used in.
