Potassium fluoride is used in metal finishing, batteries, coatings and photographic chemicals. It is utilized for the study of ion-specific swelling and de-swelling of ampholytic polymer gels as well as in the measurement of electronic polarizabilities of ions in polymers of alkali halides. It finds application in the electronic industry as a metal surface treatment product. It is used as a preservative, a food additive, a catalyzer and a water absorbing agent. In the Finkelstein reaction, it is actively involved in the conversion of chlorocarbons to fluorocarbons using polar solvents like dimethyl formamide and ethylene glycol.
