Vinylphenyldichlorosilane is primarily used in the production of silicone polymers and resins. It acts as a key intermediate in the synthesis of silane coupling agents, which enhance the adhesion between organic and inorganic materials. This chemical is also employed in the modification of surfaces, particularly in the creation of hydrophobic coatings for glass, ceramics, and metals. Additionally, it finds application in the electronics industry for the fabrication of semiconductor devices, where it aids in the formation of protective layers. Its reactivity with various substrates makes it valuable in the development of advanced materials with tailored properties.
