Vinyltrimethoxysilane is widely used as a coupling agent in the production of composite materials, enhancing the adhesion between organic polymers and inorganic substrates. It is commonly applied in the manufacturing of fiberglass-reinforced plastics, where it improves the mechanical properties and durability of the final product. In the coatings and adhesives industry, it serves as a crosslinking agent, providing better resistance to moisture, heat, and chemicals. Additionally, it is utilized in the modification of surfaces, such as glass or metal, to promote bonding with organic materials. Its application in sealants and caulks ensures improved flexibility and weather resistance. The chemical also plays a role in the synthesis of silicone resins and as an intermediate in organic synthesis processes.
