This copolymer is widely used in the production of water-repellent coatings for textiles, leather, and paper. It imparts excellent hydrophobic properties, making materials resistant to water and stains. In the automotive industry, it is applied as a protective coating for glass and mirrors to enhance visibility during rain by causing water to bead and roll off. Additionally, it is utilized in personal care products, such as hair conditioners and skin creams, to provide a smooth, non-greasy feel and improve moisture retention. Its ability to reduce surface tension also makes it valuable in industrial applications like mold release agents and anti-foaming agents.
