Uses
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.

응용 분야
용도VTMS may be used to provide superhydrophobicity to different materials like TiO2, talc, kaolin, magnesium oxide nanoparticles, ammonium phosphate and PEDOT. It modifies the surface by capping the material and creates a protective layer that is water resistant and can be used in major coating industries.
일반 설명Vinyltrimethoxysilane (VTMS) is a silane coupling agent with silicon and hydroxyl groups that can be used to enhance the wettability and improve the superhydrophobic characteristics of different composites.
