ABSTRACT:
A liquid phosphatizing composition, containing organic solvent such as 1,1,1-trichlorethane or trichlorofluoromethane, can provide phosphate coatings on metal articles. In addition to the organic solvent, the composition contains a phosphatizing proportion of phosphoric acid and a solubilizing liquid capable of solubilizing phosphoric acid in the organic solvent. Most critically, the composition contains water in an amount exceeding the proportion of phosphoric acid, yet, the water-containing liquid composition maintains liquid phase homogeneity. Phosphatized coatings of desirable water insolubility are obtained.
