Hydrofluoric acid is a weak acid that has multiple uses in industry and research. Its use as a starting material or intermediate can be found in industrial chemistry, glass finishing, silicon chip manufacturing, mining, and refining. Organofluorine chemistry provides the principal use of hydrofluoric acid. This product is also used in the production of fluorides and as an etchant and cleaning agent.


Hydrofluoric acid is incompatible with over 35 specific chemicals. Heat, glass, concrete and other silicon-bearing materials will yield silicon tetrafluoride. Carbonates, sulfides, and cyanides will yield toxic gases such as carbon dioxide, hydrogen sulfide and hydrogen cyanide. Alkalis, some oxides, fluorine and other water-reactive materials will cause strong exothermic reactions that can be violent. Hydrofluoric acid reacts with most common metals to produce hydrogen and is corrosive to many materials, including leather, rubber and many organics. Please see SDS for full safety and compatibility information.
