摘要 |
<p>A liquid composition, containing methylene chloride, can provide phosphate coatings on metal articles. In addition to the methylene chloride, the composition contains a phosphatizing proportion of phosphoric acid and a solubilizing solvent capable of solubilizing phosphoric acid in methylene chloride. 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 thereby obtained.</p> |
