This copolymer is widely used as a surface modifier and adhesion promoter in various industrial applications. It enhances the bonding properties of coatings, adhesives, and sealants, particularly on challenging substrates like glass, metals, and plastics. In the textile industry, it is employed to improve fabric softness, durability, and water repellency. Additionally, it serves as a key ingredient in personal care products, such as hair conditioners and skin creams, to provide a smooth, silky feel and improve moisture retention. Its compatibility with silicone-based formulations makes it valuable in the production of high-performance materials, including release agents and anti-foaming agents.
