SCA-S89E 3-Mercaptopropyl-Triethoxysilane (CAS No. 14814-09-6) CAS NO.14814-09-6

3-Mercaptopropyltriethoxysilane (CAS No. 14814-09-6), silane coupling agent SCA-S89E, 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. 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.

Application
3-Mercaptopropyltriethoxysilane (CAS No. 14814-09-6), silane coupling agent SCA-S89E, can improve the properties of the mineral-filled elastomer, including modulus, tensile tear strength, heat buildup, abrasion resistance, resilience, compression set cure time may be achieved with SCA-S89M. This silane chemically bonds reinforcing minerals such as silica, clay, mica talc to the polymer matrix especially the sulfur-cured metal oxide-cured rubber elastomer. It can be used as a pretreatment on minerals added at the time of compounding. Mineral-reinforced rubbers such as shoe soles, rollers, wheels, white sidewalls, wire cable insulation are the common case SCA-S89E could be used in.
