Used primarily as a key ingredient in the production of water- and oil-repellent coatings for textiles, leather, and paper. It imparts durable hydrophobic and oleophobic properties, making materials resistant to stains and liquids. Also employed in the formulation of specialty polymers for use in paints, adhesives, and sealants, where enhanced surface properties are required. Its fluorinated side chains contribute to low surface energy, making it valuable in creating anti-fouling and self-cleaning surfaces. Additionally, it finds application in the development of advanced medical devices and membranes due to its chemical resistance and biocompatibility.
