Potassium perfluorobutanesulfonate
Potassium perfluorobutanesulfonate (CAS: 29420-49-3), known as PFBS potassium salt, is a short-chain perfluorinated sulfonate surfactant featuring exceptional chemical and thermal stability. Unlike long-chain perfluoroalkyl substances, its C4 fluorocarbon tail offers a more favorable environmental profile while retaining the surface-active properties of fluorosurfactants: dramatically lowering surface tension, providing outstanding wetting on low-energy surfaces, and resisting harsh chemical environments. It is employed as a processing aid in fluoropolymer manufacturing, a wetting agent in specialty coatings and inks, and a surfactant in high-performance cleaning formulations. The electronics industry uses it in etching baths and semiconductor processing where chemical inertness is critical. With regulatory pressure favoring short-chain alternatives to PFOS, potassium perfluorobutanesulfonate has become an important C4 chemistry solution for demanding surfactant applications requiring fluorocarbon performance.
