Used as a coupling agent in polymer chemistry, particularly in the synthesis of polyurethanes and epoxy resins. It enhances adhesion between organic and inorganic materials, improving mechanical strength and durability of coatings and composites. Also serves as a chain extender or crosslinking agent due to its reactive hydroxyl and thiol groups, enabling tailored network formation in specialty polymers. Its bifunctional structure supports the development of heat-resistant and chemically stable materials used in adhesives, sealants, and protective coatings.
