Widely used in industrial applications for its exceptional water and oil repellency. Commonly found in surface treatments for textiles, paper, and leather to provide durable stain and moisture resistance. Employed in coatings for electronic devices to protect against humidity and corrosion. Also utilized in firefighting foams due to its ability to form stable films on flammable liquids. Its extreme stability makes it effective in harsh environments, though environmental persistence has led to regulatory scrutiny and efforts to find alternatives.
