3-Glycidoxypropyltriethoxysilane is a colorless to pale yellow liquid used as a versatile silane coupling agent. With a glycidyl epoxy group and triethoxysilane functionality, it acts as an adhesion promoter, coupling agent, crosslinking agent, and surface modifier. It enhances adhesion, improves compatibility, participates in crosslinking reactions, and enhances surface properties. It finds applications in adhesives, coatings, composites, electronics, fiber-reinforced plastics, glass, rubber, textiles, and leather industries.
