Abstract: The use of chelating type cation exchange resins, particularly those with iminodiacetic acid functionality, to remove dissolved multivalent cations such as iron, zinc, and chromium from used autodeposition compositions permits reuse of the autodeposition compositions without the need for added surfactant and without developing any undesirable graininess or other texture in the coatings formed. The cation exchange resins can be efficiently regenerated with 0.5 to 4% by weight aqueous hydrofluoric acid.

Abstract: An apparatus and method is provided for automated periodic removal of metal ions and contaminants from a chemical bath comprising a latex solution containing charged latex particles and having an acidic pH, used for forming a coating by autodeposition. The system includes a tank containing a chemical bath, an ion exchange column for removing the metal ion contaminants, circulating pump, metal composition sensors, and equipment for regeneration of the ion exchange column. The system particularly includes a filter located at the inlet to the ion exchange column for removing solid particulates, including coagulated latex and debris from the coating solution, while permitting the uncoagulated latex particles to pass through to the ion exchange column.

Abstract: The susceptibility to heat degradation of an autodeposited coating in which the principal organic constituents are copolymers of vinylidene chloride in which vinylidene chloride residues constitute at least half the weight of the total binder phase in the autodeposited coating is improved if the wet autodeposited coatings are rinsed, before being later dried and cured, with a water-based liquid rinse that comprises dissolved phosphate ions in a concentration that corresponds stoichiometrically to at least 0.5 g/l of tripolyphosphate ions. The water-based liquid rinse preferably has a strongly alkaline pH and also comprises dissolved organic molecules that are effective chelating agents for dissolved iron cations by reason of having in each molecule at least two carboxyl, carboxylate, and/or other hydroxy moieties.

Abstract: The use of selected cation exchange resins to remove dissolved multivalent cations ions such as iron, zinc, and chromium from used autodeposition compositions permits reuse of the autodeposition compositions without the need for added surfactant and without developing any undesirable graininess or other texture in the coatings formed. Iminodiacetate cation exchange resins are very effective for removing iron ions when they are the only multivalent ions to be removed, and can be efficiently regenerated with 0.5 to 4% by weight aqueous hydrofluoric acid. By proper choice of other cation exchange resins and operating conditions, zinc can be selectively extracted from autodeposition baths containing both iron and zinc, and either iron or zinc can be selectively displaced from the loaded ion exchange resin.
