Application

Vinylmethyldimethoxysilane is widely used as a coupling agent to enhance the adhesion between organic polymers and inorganic surfaces, such as glass, metals, or minerals. It serves as a key crosslinking component in silicone-based sealants, adhesives, and coatings, improving durability and weather resistance. Researchers also employ it as a precursor for modifying silica nanoparticles or synthesizing hybrid materials with tailored surface properties.
