  • Publication number: 20010011639
    Abstract: The present invention relates to a process for the multilayer coating of substrates with electrodeposition and powder coating materials, in which electrodeposition is used to apply at least one coat (2) of electrodeposition coating material to the substrate (1), after deposition the substrate (1) is, if desired, wholly or partially air-dried, a coat of powder coating material (3) is then applied, and finally electrodeposition coating material and powder coating material are jointly baked.
