    Abstract: A process forming an organic coating, such as an autodeposited coating, on a plurality of small metallic articles by contacting the articles with a liquid coating composition containing an organic film-forming material comprising:(A) providing a plurality of said articles, with at least some of the articles being in contact with at least one other of said articles;(B) immersing the articles into a bath of said composition under conditions such that said articles are not in conttact with another article in said composition;(C) maintaining said articles in separated form in said composition for a period of time sufficiently long for the entirety of the surfaces of said articles to be coated with said composition; and(D) collecting the coated articles in the bath in a form in which at least some of the coated articles are in contact with another of said coated articles;wherein the coating composition is capable of forming on a steel panel immersed therein a coating having a wet strength such that its rinse resistance is at least about 30 seconds.

    Abstract: An autodeposition bath for coating steel and similar metals is operated initially with a low content of dissolved iron and at a high oxidizing potential. After the iron content has increased beyond a specific level, such as 1.5 g/l, the oxidizing potential is reduced. This permits continued satisfactory operation of the bath with lower rates of iron accumulation in the bath, so that the need for bath stabilization by removing dissolved iron is deferred.

    Abstract translation: 用于涂覆钢和类似金属的自动沉积浴最初以低含量的溶解铁并处于高氧化潜能。 在铁含量增加超过特定水平（例如1.5g / l）后，氧化电位降低。 这允许在浴中持续令人满意的操作电镀铁，因此推迟了通过除去溶解的铁对浴液稳定的需要。

    Abstract: Coating compositions which can be used for depositing a coating on a metal substrate by a chemical deposition process based on aqueous emulsions of adducts of alpha, beta-ethylenically unsaturated carboxylic acids to alkane diene polymers with an acid content corresponding to 12.5 to 25% by weight of maleic anhydride calculated on the adduct. The coating compositions on deposition provide films which have excellent recoatability, excellent corrosion resistance, and permit the elimination or a reduction in the amount of conventionally used additives in a chemical deposition bath. The coating compositions can be employed in other conventional coating processes.
