Used as a key intermediate in the synthesis of fluorinated surfactants and surface modifiers. Its highly fluorinated chain provides exceptional water and oil repellency, making it valuable in coatings for textiles, paper, and electronics where moisture resistance is critical. Commonly employed in formulations for anti-fogging, anti-staining, and anti-icing applications. Also utilized in specialty polymers to enhance thermal stability and chemical resistance. Due to its low surface energy, it improves leveling and wetting properties in high-performance industrial coatings and firefighting foams.
