Used as a surface treatment agent in coatings and adhesives to improve water repellency and durability. Enhances adhesion between organic and inorganic materials in sealants and construction chemicals. Functions as a coupling agent in silicone-based formulations, increasing resistance to environmental stress. Also applied in the synthesis of specialty siloxanes for personal care products, where it contributes to smoothness and stability in cosmetic emulsions. Its hydrophobic nature makes it suitable for protective treatments on textiles and mineral surfaces.
