Allyldimethoxysilane is primarily used as a coupling agent in the production of composite materials, where it enhances the adhesion between organic polymers and inorganic surfaces. It is widely applied in the coatings industry to improve the durability and weather resistance of paints and sealants. In the rubber and plastics industry, it acts as a crosslinking agent, improving the mechanical properties and thermal stability of the final products. Additionally, it is utilized in the modification of glass fibers and fillers to ensure better compatibility with polymer matrices in reinforced composites. Its application extends to the electronics industry, where it is used in the surface treatment of semiconductors and other components to enhance performance and reliability.
