Triethoxyvinylsilane is widely used as a coupling agent in the production of composite materials, enhancing the adhesion between organic polymers and inorganic substrates. It is particularly effective in improving the mechanical properties of fiberglass and mineral-filled composites, making it valuable in the manufacturing of automotive parts, construction materials, and marine components.

In the coatings industry, it is utilized to improve the durability and weather resistance of paints and coatings, especially for outdoor applications. It also serves as a surface modifier, providing water repellency and corrosion resistance to treated surfaces.

Additionally, it is employed in the synthesis of silicone resins and adhesives, where it contributes to better cross-linking and stability. Its ability to bond with various materials makes it a key component in the development of high-performance sealants and elastomers.

In electronics, it is used as a dielectric material and in the production of semiconductor devices, where it aids in enhancing insulation properties and device reliability.
