Used as a key intermediate in the synthesis of organosilicon compounds, particularly in the production of specialty silicones for coatings and adhesives. Its reactive dichlorosilane group enables easy attachment to surfaces, making it useful in surface modification and coupling agents for composite materials. Commonly employed to enhance adhesion between organic polymers and inorganic substrates. Also utilized in the development of silane-based primers and water repellents due to its ability to form stable siloxane bonds.
