Used as a coupling agent in silicone-modified resins and coatings, enhancing adhesion between organic polymers and inorganic surfaces. Commonly applied in dental composites and prosthetics to improve mechanical strength and durability. Also utilized in specialty adhesives and sealants where moisture resistance and thermal stability are required. Functions as a surface modifier for glass fibers and mineral fillers in composite materials. Enables better dispersion of fillers in polymer matrices, improving processing and final product performance.
