Used as a coupling agent in hybrid organic-inorganic materials, this compound enhances adhesion between organic polymers and inorganic surfaces such as glass, metals, and fillers. Its epoxy functionality reacts with amine or hydroxyl groups in resins, while the alkoxysilane groups hydrolyze and condense on metal oxide surfaces, forming strong covalent bonds. Commonly applied in coatings, adhesives, and composite materials to improve mechanical strength, moisture resistance, and thermal stability. Also utilized in sealants and encapsulants where durability and adhesion under harsh conditions are required.
