The typical concentration of VTMS in industrial products is from 1 to 2%. VTMS undergoes reactions, resulting in minimal or no residual chemical in the final products. It serves as a coupling agent for plastics and wire and cable pipes, acts as a moisture scavenger in sealants, and functions as a co-monomer in latex dispersions to enhance adhesion on inorganic surfaces. VTMS is managed within closed systems (hard piped) in manufacturing environments, and it is not used in consumer products.Information on 20 consumer products that contain Trimethoxyvinylsilane in the following categories is provided:
