摘要： The use of selected cation exchange resins 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. 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沉积组合物中除去溶解的多价阳离子如铁，锌和铬可以重新利用自沉积组合物，而不需要添加表面活性剂，并且不会在所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，锌可以从含有铁和锌的自沉积浴中选择性提取，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 invention concerns a process for forming an autodeposition coating on a metallic substrate by applying an autodeposition composition from a motile source thereof such as by spraying or by treating the surface with a continuous stream of the autodepositing composition. The figure shows an embodiment of the invention wherein the autodepositing composition is applied as a continuous stream along a metallic surface. The autodepositing composition is stored as an autodepositing bath (2) in a vessel (4). The object to be coated, typically a panel (6) having a metallic surface (8), is positioned so as to be impinged by a stream (10) of the autodeposition composition. The stream (10) is formed by passing the autodepositing composition from the bath (2) through a conduit (12) by the pressure generated by a pump (14). The autodepositing composition proceeds through the conduit (16) and is evacuated ouf of an exit port (18).

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： 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.
