Used as a coupling agent in the production of silicone polymers and resins, enhancing adhesion between organic and inorganic materials. Commonly applied in surface treatment of fillers and reinforcements like glass fibers, improving compatibility with polymer matrices. Utilized in the synthesis of organosilicon compounds, serving as an intermediate in the manufacture of silicone rubbers, sealants, and coatings. Also employed in the modification of silica surfaces for chromatographic applications, improving separation efficiency. Its reactive groups enable grafting onto various substrates, making it valuable in creating functionalized materials for industrial and research purposes.
