Resulting from a joint effort by Dürr Systems GmbH, Stuttgart, and Henkel AG & Co., Dusseldorf, the new process can lower costs and lower energy consumption. Aquence, an "auto deposition" process that generates corrosion protection coatings of variable film thicknesses, also provides better quality and eliminates a series of processes, say the companies. Autophoretic deposition occurs out of an aqueous organic emulsion directly onto a degreased material surface.
When applied, the process generates the coating of iron surfaces only; plastic materials remain uncoated. The process makes it possible to evenly coat complex structures both internally and externally, as well as coat complete assemblies of parts of different materials.
