Used as a coupling agent in sol-gel processes and surface modification of inorganic materials. Enhances adhesion between organic polymers and inorganic substrates such as glass, metals, and silica-based surfaces. Commonly applied in coatings, sealants, and composite materials to improve mechanical strength and durability. Also utilized in the formulation of silane-based primers and adhesives where moisture resistance and long-term stability are required. Its amine functionality allows for further chemical derivatization or catalytic activity in hybrid material synthesis.
