摘要： Autodepositing compositions of the type that form coatings which tend to crack in the wet stage are modified by including in the composition a fugitive plasticizer, such as 2,2,4-trimethylpentanediol-1,3 monoisobutyrate, tributoxyethyl phosphate, ethylene glycol monohexyl ether, diethylene glycol monohexyl ether, or a mixture of phenyl glycol ethers.
摘要翻译：通过在组合物中包含短效增塑剂，例如2,2,4-三甲基戊二醇-1,3-单异丁酸酯，三丁氧基乙基磷酸酯，乙二醇单己基醚，乙二醇单己基醚等，改性形成在湿阶段中易于开裂的涂层的类型的自动沉积组合物，二甘醇单己基醚或苯二醇醚的混合物。

摘要： An outodepositing coating process wherein a coating bath containing an acidic aqueous coating composition comprising as essential ingredients: (1) an acid; (2) an oxidizing agent; and (3) an aqueous dispersion of coating forming resin particles and surfactant, which surfactant is subject to being slowly altered by the acidic oxidizing environment in the metal coating bath resulting in the buildup of reaction products in the bath, which bath is maintained in continuous coating forming operability by replenishing in a manner which prevents the deterioration of the coating quality of the bath. The coating composition and replenishing composition may also contain as an optional ingredient an aqueous dispersion of pigment and surfactant and may also contain non-essential ingredients, which non-essential ingredients may increase in concentration as the bath is operated until a deleterious effect is asserted on the coating formation. The coating quality of the replenished bath is maintained by the addition of an aqueous surfactant composition and by operating the replenished bath at an elevated redox potential or by removal of the altered surfactant.
摘要翻译：一种沉积涂覆方法，其中包含含有作为必要成分的酸性水性涂料组合物的涂料浴：（1）酸; （2）氧化剂; 和（3）涂层形成树脂颗粒和表面活性剂的水分散体，该表面活性剂在金属涂层浴中被酸性氧化环境缓慢改变，导致反应产物在浴中积聚，该浴保持在连续通过以防止浴的涂层质量劣化的方式补充涂布成形可操作性。涂料组合物和补充组合物还可以含有颜料和表面活性剂的水性分散体作为任选成分，并且还可以含有非必需成分，非必需成分可以在浴操作时浓度增加，直到有害影响被证实为涂层形成。通过加入水性表面活性剂组合物并通过在升高的氧化还原电位下操作补充的浴或通过除去改变的表面活性剂来维持补充浴的涂层质量。
