ABSTRACT:
The corrosion resistance, and also often the heat resistance, of a autodeposited coating in which the organic binders are predominantly copolymers of vinylidene chloride containing at least 50% vinylidene chloride can be improved by including another type of organic resin binder in the autodeposition bath in sufficient amount to constitute at least 2 up to as much as about 40% of the total of the PVDC and the other organic resin binder. Results can be further improved by rinsing the uncured autodeposited coating with an aqueous treatment solution that has a pH between 7 and 11 and contains between 0.01 and 5% of anions derived from multifunctional organic acids, preferably anions of 1-hydroxyethylidene-1,1-diphosphonic acid, citric acid, tartaric acid, and/or oxalic acid before drying the coating.
