Applications

(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.

Notes

Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Store under inert gas. It is sensitive to moisture and air. Incompatible with oxidizing agents.
