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： An acidic aqueous coating composition containing an organic coating-forming material forms on a metallic surface immersed therein a coating, the weight or thickness of which is related to the time the surface is immersed in the composition. The coating composition, which tends to become unstable as a result of the build up of metal ions in the composition, is stabilized by removing the metal ions with an ion exchange material. Also, in maintaining stability, anionic and/or nonionic surfactants or dispersing agents, which are present in the composition to disperse the organic-coating forming material, are added to the composition in an amount in excess of that which is added to replenish the organic coating-forming material as it is consumed during use. Also, coating compositions treated with the ion exchange material tend to produce coatings which have a textured or grainy appearance. The texturing of coatings can be avoided by contacting the coating composition with the ion exchange material in the presence of a cationic surfactant or an amphoteric surfactant which has cationic properties in the acidic aqueous coating composition, or other material which maintains the relatively small particles of the organic coating-forming material in the composition.

摘要： In a process wherein an organic coating is formed on a metallic surface by immersing the surface in an acidic aqueous coating composition containing dispersed particles of an organic coating-forming material from which the particles are deposited on the metallic surface forming an organic coating which increases in thickness the longer the surface is immersed in the composition and wherein the temperature of the coating composition tends to rise with the result that the quality of coatings formed therefrom is affected adversely, particularly when coating worked or roughened metal surfaces, the improvement comprising maintaining the temperature of the coating composition at a temperature within the range over which the rate of change in the rate of film build is substantially constant thereby improving the quality of the coating formed by the deposition of coating-forming particles, including reducing or preventing the tendency of the composition to form coatings which contain pinholes and/or craters.

摘要： Method and apparatus for agitating an acidic aqueous coating composition containing dispersed particles of an organic coating-forming material are disclosed. Movable vanes are disposed beneath the surface of a bath of the composition. The vanes have a relatively large surface area and are moved through the bath at low speed so that the shear stress imposed on the dispersed particles is minimized. This prolongs the stability of the composition.
