Used as a surface modifier in silicone-based formulations to improve slip, leveling, and water repellency. Commonly applied in coatings, inks, and adhesives to reduce surface tension and enhance surface smoothness. Also functions as a compatibilizing agent in polymer blends and is utilized in personal care products for its softening and shine-enhancing properties. Its hydrophobic nature makes it suitable for moisture-resistant treatments in textiles and construction materials.
