Overview of Hydrofluoric Acid 20%
Hydrofluoric Acid 20% is a diluted, corrosive acid solution composed of hydrogen fluoride mixed with water. It is widely used in controlled industrial applications where a lower-strength fluoride source is required, offering effective glass etching, metal cleaning, silica removal, and chemical synthesis with better handling safety compared to higher concentrations.
This clear, pungent-smelling liquid reacts strongly with metals, silica, and minerals, making it valuable in surface treatment, semiconductor cleaning, and specialised manufacturing processes. ChemicalBull supplies high-quality Hydrofluoric Acid 20% suitable for regulated industrial and laboratory applications.
You may also like Sodium Fluoride, Hexafluorosilicic Acid, Ammonium Tetrafluoroborate, and Tin Fluoride for various fluoride-based industrial uses.
