Widely used as a coupling agent in the production of composite materials, enhancing the adhesion between organic polymers and inorganic substrates. Commonly applied in coatings and sealants to improve water resistance and durability. Plays a key role in the modification of fillers and pigments, ensuring better dispersion and stability in various formulations. Utilized in the manufacturing of adhesives to increase bond strength and longevity. Also employed in the treatment of glass fibers to improve their compatibility with resin matrices in reinforced plastics.
