CAD - Chemical Agents Directive, Art. Ammonium bifluoride (CAS No. Linear Formula NH 4 HF 2. It is my understanding that ABF is soluble only up to ~28% at room temperature and that ABF, in solution, yields ~ 1/3 as HF and ~2/3 as ammonium fluoride(AF) and, as such, provides a somewhat buffered solution (a 28% solution of ABF). And we faced with the project about chemical factory. The changing trend toward matt drawing on glass and metal is also bolstering the ammonium bifluoride market. Evaporation Rate (BuAc=1): No information found. 2005. Like all fluoride salts, it is moderately toxic in both acute and chronic overdose.
