Description and features
Silqon VTMO (Vinyltrimethoxysilane) is a powerful organosilane coupling agent, crosslinking agent, and surface modifier that enhances the adhesion of organic polymers to inorganic surfaces. This versatile agent is used to improve the chemical resistance, moisture resistance, and mechanical properties of coatings, sealants, plastics, and electronic materials.
Moreover, its reactive vinyl and methoxy functional groups enable strong chemical bonds, which in turn increase durability and resistance in treated materials. As a result, industries ranging from construction to electronics consistently rely on Silqon VTMO for its efficiency and reliability.
