Definitions
- the invention relates to a method for coating electrically non-conductive plastic parts, for example Made of polypropylene, polyethylene or ABS plastic, where the surface of the plastic parts in a first Electrostatic spray painting (ESTA) operation is pretreated and then a coat of paint electrostatic spray painting, especially high-speed atomization a hydro lacquer.
- ESA Electrostatic spray painting
- Electrically non-conductive plastic parts are currently coated by first diving or Spray painting with an electrically conductive primer provided and then spray-painted electrostatically become.
- the spray painting that is widely used for priming allows it doesn't, the material particles through electrostatic To direct forces to the part to be treated, since the Parts are initially not electrically conductive. Therefore when priming the overspray relatively large, resulting in increased Material consumption and pollution of the environment in which the priming takes place.
- the primer itself must have special adhesion promoters and conductive Contain substances and is therefore expensive. Come in addition, that painting with two different materials is complex.
- the invention is based on the problem of a method for Coating of electrically non-conductive plastic parts to develop after which an electrostatic Spray painting (ESTA) is possible without this Plastic parts beforehand by an electrical primer must be made conductive.
- ESA electrostatic Spray painting

Claims (2)
- Procédé pour revêtir des pièces plastiques électriques non conductrices, par exemple en polypropylène, polyéthylène ou plastique ABS, dans lequel la surface des pièces plastiques est soumise à un traitement préalable dans une première passe, pour une application par pulvérisation électrostatique, puis on procède à l'application d'une couche par pulvérisation électrostatique, en particulier par pulvérisation d'une hydrolaque à grande vitesse de rotation, caractérisé en ce que le traitement préalable de la surface s'effectue par fluoration.
- Procédé selon la revendication 1, caractérisé en ce que le traitement préalable est réalisé dans un récipient fermé, avec un mélange gazeux constitué d'un gaz inerte et d'une fraction de fluor de 0,4 à 3 % en volume, pendant un laps de temps de 5 à 180 secondes.
