Used primarily as a surface modifying agent, it imparts water repellency and improves adhesion properties to various materials. In the coatings industry, it enhances the durability and performance of protective layers on surfaces like glass, metals, and ceramics. It is also employed in the production of silicone polymers, where it acts as a key intermediate to modify the properties of the final product. Additionally, it finds application in the treatment of fillers and pigments to improve their dispersion and compatibility in polymer matrices. Its hydrophobic characteristics make it valuable in creating moisture-resistant coatings for construction materials.
