Used as a surface modifying agent in the production of silica-based materials, enhancing compatibility between organic polymers and inorganic substrates. Commonly applied in adhesives, sealants, and composite materials to improve mechanical strength and moisture resistance. Also serves as a coupling agent in rubber and tire manufacturing, promoting better filler dispersion and reducing energy loss. Its amino functionality enables catalytic activity in certain polymerization processes and supports use in specialty coatings requiring improved adhesion and durability.
