Triethoxysilane is widely used as a coupling agent in the production of composites and adhesives. It enhances the bonding between organic polymers and inorganic materials, making it valuable in the manufacturing of reinforced plastics, coatings, and sealants. In the construction industry, it is applied to improve the adhesion of coatings to concrete and metal surfaces, increasing durability and resistance to environmental factors. Additionally, it serves as a precursor in the synthesis of silicone resins and elastomers, which are utilized in various industrial applications. Its ability to modify surfaces also makes it useful in the preparation of glass and ceramic materials for improved performance in electronics and optics.
