摘要： 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.

摘要： 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.

摘要： 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.
摘要翻译：使用选择的阳离子交换树脂从使用的自动沉积组合物中除去溶解的多价阳离子离子如铁，锌和铬可以重新使用自沉积组合物，而不需要添加表面活性剂，并且不会在形成的涂层中产生任何不期望的颗粒状或其它质地。亚氨基二乙酸盐阳离子交换树脂当它们是唯一要除去的多价离子时非常有效，并且可以用0.5至4重量％的氢氟酸水溶液有效再生。通过适当选择其他阳离子交换树脂和操作条件，可以从含有铁和锌的自沉积浴中选择性提取锌，并且铁或锌可以从负载的离子交换树脂中选择性地置换。

摘要： The quality of coating in autodeposition from solutions in which the coating is predominantly derived from epoxy resins can be improved in two ways, which can be used jointly or separately: A blocked isocyanate is used as cross linking agent for the epoxy resin, and a surfactant that prevents the occurrence of phase separation during drying of the coating is used. Preferably the surfactant is a fluoroaliphatic polymer ester.

摘要： Pinhole and blister formation during autodeposition coating of galvanized steel and similar zinciferous surfaces can be greatly reduced by exposing the zinciferous surfaces to a pinhole inhibiting aqueous HF solution containing a suitable additive before using an autodeposition process itself. The most effective additives are boric acid, polyphosphonic acids, and polyethyleneimine.

摘要： 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.
