Coil coating method using powder coat dispersions (powder slurries)

摘要

A coil coating process in which a metal strip is coated continuously on one or two sides with at least one coating material and then the applied coating film(s) is (are) cured, at least one of the coating materials being a pigmented or unpigmented powder coating dispersion (powder slurry) and the applied powder slurry film(s) being heated so that (i) the water present therein evaporates, (ii) the finely divided dimensionally stable constituents of the powder slurry which remain melt and coalesce, and (iii) curing is carried out thermally and/or with actinic radiation, to give at least one clearcoat and/or at least one color and/or effect coat.
