Abstract: A method is described for the coating of substrates by the application of a liquid coating compound and subsequent curing, which is characterised in that there are added to the coating compound one or more polybutenes (C4-polyolefins) with a molecular weight of 200 to below 500, in a quantitative proportion of 0.5 to 10 wt. %, referred to the solids content of the coating compound, in order to improve the flow properties. The liquid coating compounds are also described.

Abstract: Known processes for coating hollow bodies such as cans are problematical in terms of productivity and contamination caused by high rotational speeds of the application rolls due to lacquer splashes and lacquer mist. These problems are solved by means of a process and a device for the application of several coatings to cylindrical hollow bodies by rolling the hollow bodies on an application device having a lacquer film wherein several hollow bodies roll on the lacquer film one after the other and wherein, for the application of at least the first coat of lacquer such hollow body rolls in the lacquer film which is progressively reduced by separation of lacquer on the application of lacquer to the preceding hollow body or bodies.

Abstract: Aqueous, heat-curable coating material, containing as vehicle 85 to 40 weight percent of a mixture of a fatty acid-free, acidic epoxide resin phosphate ester with an acid number of 10 to 150, prepared from an epoxide group-containing polyglycidyl ether and/or a polyglycidyl methacrylate resin with more than 1.3 epoxide groups per molecule and an epoxide equivalent weight of 180 to 5,000 and a phenolic resin-modified, carboxyl group-containing, oil-free polyester with an acid number of 15 to 175 and an OH number of 15 to 175, 0 to 25 weight percent of an epoxide resin graft copolymer with an acid number of 30 to 200, prepared from an epoxide group-free reaction product of fatty acid-free polyglycidyl ethers with more than 1.3 epoxide groups per molecule and an epoxide equivalent weight of 1,000 to 5,000 with .alpha.,.beta.

Abstract: In order to coat hollow bodies, which are open at one end, such as a metal can provided with a bottom, with a lacquer or the like, the hollow bodies are passed in a continuous operating cycle through en electrophoretic immersion bath in such a way, that they are rapidly and completely flooded with immersion bath liquid, so that they can be coated electrophoretically with a wet film in the immersion bath. After a sufficiently long coating time, the hollow bodies are lifted out of the immersion bath and the immersion bath liquid, contained in them, is poured out. The hollow bodies, so coated, are carried at a distance from each other to a drying kiln, in which they are dried, whereupon they can be printed or labelled.

Abstract: A device for holding hollow bodies of electrically conductive material, such as cans of sheet metal, while they are conveyed through an electrophoretic dip bath, is provided with a conveying element which runs through the dip bath, which seizes in succession the open ends of the individual hollow bodies and temporarily holds them. For this purpose, at least three electrically conductive holders for the individual hollow bodies are arranged on the conveying element, which holders are rotatable about a shaft and form gripping devices for seizing, in a detachable manner, the edge of a respective hollow body. The holders are preferably conical pegs, on the surface of the sheath of which threads are arranged as gripping devices, which threads are interrupted at at least one point.
