登记用途：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、Household Products: Information on 20 consumer products that contain Trimethoxyvinylsilane in the following categories is provided。
