Used primarily as a chemical intermediate in the production of silicon-based polymers and resins. It serves in the synthesis of silanes and siloxanes, which are key components in manufacturing silicone fluids, rubbers, and resins. Commonly employed as a cross-linking agent in room-temperature vulcanizing (RTV) silicone systems, enhancing durability and water resistance. Also utilized as a surface treatment agent to impart water repellency to materials like glass, ceramics, and textiles. Plays a role in the semiconductor industry for depositing silicon-containing films through chemical vapor deposition processes. Its reactivity with moisture makes it effective in creating hydrophobic coatings, though it requires careful handling due to corrosive by-products.
