Patent ID: 7083830

Claim:
A process for the production of special effect base coat/clear coat two-layer coatings on substrates, comprising the successive steps (a) applying a special effect base coat layer of a liquid special effect base coat onto the substrates in one or more successive spray passes, (b) optional drying or curing of the special effect base coat layer, (c) applying a clear coat layer, and (d) curing the clear coat layer, wherein, at least in the final spray pass, application of the special effect base coat proceeds by electrostatically-assisted high-speed rotary application using at least one high-speed rotary coating device comprising a high-speed rotary bell having a housing firmly connected to an electrode ring via a fastening device by means of a bearing connection, wherein the electrode ring is rotatably positioned around the high-speed rotary bell and used for external electrostatic charging of the effect base coat spray mist and performs rotational movements about the common axis of rotation with the high-speed rotary bell.
