Used primarily as a surfactant in various industrial applications due to its excellent wetting and spreading properties. It is often employed in the formulation of coatings, paints, and inks to enhance surface coverage and adhesion. Additionally, it serves as a key ingredient in firefighting foams, where it helps to suppress flammable liquid fires by forming a stable film over the fuel surface. In the electronics industry, it is utilized in the production of fluoropolymers and as a component in cleaning agents for delicate electronic components. Its chemical resistance and low surface tension make it valuable in the manufacturing of water- and oil-repellent textiles and protective coatings.
