Abstract

The invention concerns a powder-coating process and device, plus a coating powder for use in the process, the process calling for a suspension of the coating powder to be atomized and sprayed on to the surface to be coated, (1) the powder being suspended in a liquefied gas which is kept liquefied under a pressure of at the most 20 bar and (2) the liquid gas being allowed to vaporize before, during or after the suspension is atomized.
