Used as a coupling agent in the production of adhesives, sealants, and coatings to enhance adhesion between organic polymers and inorganic materials. It improves the mechanical properties and durability of composites by promoting better bonding at the interface. Commonly applied in the manufacture of silicone-modified polymers, where it acts as a crosslinking agent to increase thermal stability and water resistance. Also utilized in surface treatment of fillers and pigments to improve dispersion in polymer matrices, ensuring uniform performance in end products.
