Used as a high-performance surfactant and surface modifier in specialty coatings and firefighting foams due to its strong fluorinated character. Enhances oil and water repellency on surfaces, making it suitable for protective treatments on textiles, electronics, and aerospace materials. Also functions as a building block in heat-resistant and chemically stable polymers. Its fluorocarbon chains provide excellent thermal stability and low surface energy, beneficial in non-stick and anti-fouling applications.
