Used in the production of fluoropolymers and fluoroelastomers, which are essential in manufacturing high-performance seals, gaskets, and linings resistant to heat, chemicals, and weathering. Commonly employed as a surfactant in coating formulations, including those for architectural and industrial finishes, due to its ability to improve wetting and leveling. Applied in fire-fighting foams for its effectiveness in suppressing flammable liquid fires. Also utilized in electronics manufacturing, particularly in etching and cleaning processes, where stability and precision are critical.
