Description

CAS: 31001-77-1 | C6H16O2SSi | 180.337 g/mol

(3-Mercaptopropyl)methyldimethoxysilane is used as coupling agent to improve the adhesion of sulfur cured elastomers (polysulfide, polyurethane sealants) to inorganic fillers (such as silica, glass, clay, mica), fiberglass and surfaces. It is also used as a pretreatment on minerals or added at the time of compounding and to improve low-rolling resistance in silica-reinforced tire tread compounds.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand.
