Use: It is an anionic fluorinated surfactant, which has higher surface activity, lower surface tension, lower critical micelle concentration and high thermal stability than ordinary fluorocarbon surfactants. It can be widely used in chromium fog inhibitor, fluorin fire extinguishing agent, foaming agent and other fields. The amount of chromium mist inhibitor used: 0.1-0.4 g of potassium perfluorinated hexyl ethyl sulfonate is added per liter of plating bath.
