Used as a highly effective surfactant and surface modifier in specialty coatings and firefighting foams due to its strong oil- and water-repellent properties. Provides excellent film-forming ability and surface tension reduction, making it suitable for use in fluoropolymer dispersions and high-performance lubricants. Also employed in electronic and aerospace applications where thermal stability and chemical resistance are critical. Its fluorinated structure enhances durability in harsh environments and improves performance in water- and stain-resistant treatments for technical textiles and industrial materials.
