Abstract: A method and apparatus are described for removing iron cations and/or zinc cations from an autodeposition coating bath by passing a limited number of bed volumes through a column containing a gel type SAC IEX resin when iron cations are to be removed and passing a substantially larger number of bed volumes through the column when zinc cations are to be removed. To prevent clogging when zinc cations are being removed the direction of the flow through the column is periodically reversed.

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.

Abstract: A reaction rinse containing strong alkali, betaine surfactants, and a complexing agent for iron enhances the gloss of a dried and cured autodeposited coating that is contacted with the reaction rinse while still wet, particularly if the autodeposited coating consists predominantly of a copolymer of vinylidene chloride.
