Vinyltrimethoxysilane serves as a coupling agent in the modification of surfaces and interfaces. It acts by forming a strong covalent bond with inorganic materials, such as glass, metal, or mineral fillers, and organic polymers. This allows for improved adhesion and compatibility between dissimilar materials. At the molecular level, vinyltrimethoxysilane reacts with hydroxyl groups on the surface of substrates, leading to the formation of silanol groups that can further condense to create a stable siloxane network. This network provides a bridge between the organic and inorganic components, resulting in enhanced mechanical properties and resistance to moisture and environmental degradation.
