Definitions

  • the present invention relates to a novel process for repainting multicoat color and / or effect paint systems containing at least one color and / or effect basecoat (A), prepared from at least one aqueous basecoat (A), and at least one clearcoat (B) prepared from at least one liquid clearcoat (B).
  • the present invention relates to a novel process for overcoating by means of electrostatic spray application (ESTA) produced, damaged or undamaged, multicoat color and / or effect paint systems at the automobile manufacturer in the line.
  • ESA electrostatic spray application
  • EP 0 521 040 B2 is a method for producing a multi-layer refinish in the usual sense, in which one applies in the area of the damaged area in the series coating initially a pigment-free, aqueous, film-forming coating agent before the repair water-based paint is applied.
  • the coating agent may be a pigment-free extract of the repair water-based paint.
  • a clearcoat is then applied wet-on-wet to the waterborne basecoat, after which the existing coats are cured together. This process represents a significant advance in refinishing in the usual sense.
  • the known refinishing process can not solve the above-mentioned problems that occur when overpainting color and / or effect multicoat paint systems in line at the car manufacturer, because it is this very different amounts of coating materials and a very different logistics required than for the refinish in the usual sense, which is carried out especially in car paint shops.
  • the object of the present invention is to provide a novel process for recoating multicoat color and / or effect paint systems, in particular by means of electrostatic spray application (ESTA) and curing of multicoat paint systems comprising at least one color and / or effect basecoat (A) prepared from at least one Waterborne basecoat (A), and at least one clearcoat (B), prepared from at least one liquid clearcoat (B), which no longer has the disadvantages of the prior art and the pneumatically wet-in-wet applied and cured, color and / or multicoat paint systems which do not suffer any disadvantageous hue shift and / or disadvantageous change in the optical effect, in particular the metallic effect, in comparison with the original or OEM finishes.
  • ESA electrostatic spray application
  • the multicoat paint systems produced with the aid of the new process should adhere very well to OEM (OEM) finishes.
  • the new process should be especially suitable for overcoating OEM (OEM) paints by the car manufacturer, where problems quite different from those encountered in car refinishing in the usual sense occur.

  • the process according to the invention is used for overpainting multicoat color and / or effect, preferably color and effect or effect, multicoat systems. This can be done for repair purposes, for example if the multi-layer coatings have been damaged by mechanical and / or chemical action. However, the overcoating can also be carried out with undamaged multi-layer coatings, for example if a change, in particular adaptation, of the hue and / or the optical effect is or are required.
  • the multicoat paint systems can provide protection, decoration, increase of scratch and abrasion resistance and corrosion resistance, improvement of cleaning performance, improvement of demolding and reduction of adhesion, generation of a Anti-fog effect, the generation of anti-reflection properties and / or increasing the bursting pressure serve.
