Ammonium Polyfluoride Advantages

-It is a two-in-one product. It can replace both HF and ammonium bifluoride; it was developed with the idea of replacing both products in customers using both material, basically glass etching companies.

Ammonium Polyfluoride is a mixture between HF and Ammonia, which has proven very effective in Aluminium Polishing.

-It can also the ammonium bifluoride; its main advantage is the fact that ammonium polyfluoride is liquid and has no variations with time, while ammonium bifluoride may eventually cake , as a solid acid salt. Therefore it can be used immediately in production.

-It is far less aggressive than HF., therefore it is better used in many aplications. The Ammonium Polyfluoride is just toxic and corrosive, simply (not +). Then it considered safer than HF.

-Practically it has no vapor pressure, hence it is easier to handle from the standpoint of industrial hygiene than HF as leakage are unknown of.

-For these physical / chemical reasons, it allows longer storage and more capacity in vessels containing it, as DDF ammonium polyfluoride may for instance be supplied in 1200 kg IBC. Ammonium Polyfluoride has a higher content of HF (around 80%) but it may be transported in IBC. It is far more powerful and performing than a weaker acid. At the end of the day, it is a HF 80% with a mask for Ammonium Bifluoride

It may be considered as Ammonium Bifluoride liquid.

-From a logistics standpoint, it is more manageable.

-It is easier to dose than a solid, a pump is required and nothing more. More accurate dosing hence allowing for better handoling.

-Works particulary well in: Aluminium Polishing, pickling and Aluminium pre-treatment. Also in any heavy duty metal surface treatment, and in general in all acid cleaners, specially in aluminium wheel cleaner.
