Used primarily as a surfactant and surface treatment agent in industrial applications, this compound imparts water and oil repellency to surfaces. It is applied in coatings for textiles, paper, and leather to enhance stain resistance and durability. Commonly found in formulations for fire-fighting foams due to its ability to stabilize foam and suppress fuel-based fires. Also utilized in semiconductor manufacturing and electronic devices for its dielectric properties and chemical stability. Its fluorinated chain provides exceptional thermal and chemical resistance, making it suitable for harsh environments. Limited in consumer products due to environmental persistence concerns.
