ABSTRACT:
The disclosed organic ammonium phosphate salt concentrates can be diluted with water in the weight ratio of from 1:5 to 1:250 (concentrate:water) and used in bath, spray, or steam phosphatizing (sometimes called "phosphating"). These concentrates and the resulting diluted solution are reasonably pH-stable in the pH range of 3.0 to 5.5. Preferably, the concentrates contain a buffer, various surfactants, and, particularly for low temperature use (e.g. 20.degree.-55.degree. C.) an accelerator system. The concentrates are well suited to automatic dispensing of a phosphatizing spray or make-up solution (for a bath); they are efficient at low temperatures; and they have good storage stability.
