Abstract

Beim Lackieren von Werkstücken, insbesondere von Fahrzeugkarosserien, werden in an und für sich bekannter Weise nacheinander die folgenden Lackschichten aufgebracht:

  • eine Grundlackschicht in einem elektrophoretischen Tauchverfahren, eine Funktionsschicht, eine Wasser-Basislackschicht und eine Klarlackschicht. Zur umweltfreundlichen Gestaltung dieses Verfahrens, insbesondere zur Vermeidung von Lösemittel-Emissionen und Lackschlämmen, wird die Funktionslackschicht ebenfalls in einem elektrophoretischen Tauchverfahren aufgebracht und die Klarlackschicht als Pulver-Lack elektrostatisch aufgesprüht, der nachträglich eingebrannt wird. Insgesamt lassen sich so gegenüber bekannten Verfahren die Lösemittel-Emissionen auf etwa ein Sechstel und die Lackschlammbildung auf etwa ein Drittel des früheren Wertes verringern.
    • When painting workpieces, in particular vehicle bodies, the following layers of paint are applied in a manner known per se:
  • a base coat in an electrophoretic immersion process, a functional coat, a water basecoat and a clear coat. In order to design this process in an environmentally friendly manner, in particular to avoid solvent emissions and paint sludge, the functional paint layer is also applied in an electrophoretic immersion process and the clear coat is sprayed on electrostatically as a powder paint, which is subsequently baked on. Overall, compared to known processes, the solvent emissions can be reduced to around one sixth and the paint sludge formation to around one third of the previous value.
