This chemical is primarily used as a coupling agent in the formulation of adhesives, sealants, and coatings. It enhances the adhesion between organic polymers and inorganic substrates, such as glass, metals, and ceramics. In the production of composite materials, it improves the compatibility and dispersion of fillers within the polymer matrix, leading to better mechanical properties. Additionally, it is employed in surface modification to create hydrophobic or functionalized surfaces, which are useful in applications like water repellency or chemical resistance. Its triethoxy groups enable it to form stable bonds with surfaces, making it valuable in nanotechnology and advanced material science.
