Hydrofluoric Acid 40%

Description :

Overview of Hydrofluoric Acid 40%

Hydrofluoric Acid 40% is a highly reactive and corrosive industrial acid composed of hydrogen fluoride diluted in water. Known for its ability to dissolve silica and metal oxides, it plays a critical role in glass etching, metal finishing, semiconductor manufacturing, petroleum refining, and chemical synthesis.

This chemical appears as a clear, sharp-smelling liquid and must be handled with strict safety control due to its ability to penetrate skin and react with calcium in body tissues. ChemicalBull supplies high-purity Hydrofluoric Acid 40% suitable for regulated industrial use, research laboratories, and specialised manufacturing applications.

You may also like Fluoroboric Acid, Sodium Fluoride, Ammonium Bifluoride, and Potassium Fluoride Anhydrous to support advanced fluoride-based industrial systems.
