Used as a coupling agent in silicone-modified resins and coatings, enhancing adhesion between organic polymers and inorganic surfaces. Improves durability and moisture resistance in sealants and adhesives. Commonly applied in automotive and aerospace coatings where thermal stability and strong substrate bonding are required. Also functions as a crosslinker in hybrid organic-inorganic materials, promoting network formation in sol-gel processes.

Additionally, used to improve properties of nanocomposites by aiding the dispersion of silica particles in polymer matrices, resulting in enhanced impact resistance and material durability.
