Used primarily as a surface-modifying agent, it enhances the hydrophobic properties of materials. Applied in coatings, it improves water resistance on surfaces like glass, ceramics, and metals. In the production of adhesives and sealants, it increases durability and resistance to environmental factors. It also serves as a key intermediate in the synthesis of organosilicon compounds, which are utilized in various industrial applications, including electronics and pharmaceuticals. Its ability to modify surface characteristics makes it valuable in creating specialized materials with tailored properties.
