Application: 


Ammonium bifluoride is a component of some etchants.
Ammonium bifluoride has been considered as an intermediate in the production of hydrofluoric acid from hexafluorosilicic acid. Thus, hexafluorosilicic acid is hydrolyzed to give ammonium fluoride.
The resulting ammonium bifluoride is converted to the sodium bifluoride, which thermally decomposes to release HF.

Packing:  woven bag as 25kgs per bag. Suitable for long distance transportation.
