Molybdenum in Iron phosphating

Is Molybdenum compound essential for iron phosphating. to reduce sprayer corrosion, we have introduced MO. at times, we doubt that it slows down the phosphating process. what is the minimum concentration recommended? is the discharge a pollutant? please advise.

Dear Mr. Chari:

MO is not the suitable additive for iron phosphating I suggest you add ammonium molybdate instead. By the way this is an accelerator for iron phosphating with beautiful blue color. The molybdate concentration can be as low as 0.5 g/L.

Which chemicals can be added to increase what will be the life of metal on application on ammonium mo? Will it help in increase in metal life? If yes for how many years? Strength of phosphating along with ammonium molybdate.
