Used as a coupling agent in silicone-modified resins and coatings, enhancing adhesion between organic polymers and inorganic surfaces. Commonly applied in water-repellent treatments for glass, ceramics, and metals. Facilitates crosslinking in silane-based adhesives and sealants, improving durability and moisture resistance. Also employed in the synthesis of functionalized silica for chromatography and as a surface modifier in nanomaterials to improve dispersion in polymer matrices.
