Definitions

  • the present invention relates to a method for producing a coated substrate by applying to the substrate at least one coating agent which comprises a plastic selected from a group consisting of polyethylene (PE), polypropylene (PP), thermoplastic polyolefins (TPO) or mixtures from it, as well as a corresponding plastic component.
  • a plastic selected from a group consisting of polyethylene (PE), polypropylene (PP), thermoplastic polyolefins (TPO) or mixtures from it, as well as a corresponding plastic component.
  • plastics now account for between 15 and 20 percent by weight and the trend is increasing. These are often exterior and interior parts that receive their corresponding visual, haptic and functional properties through a coating.
  • quality and economy as well as resource efficiency, but also the global competitive pressure, require ever more economical, sustainable and flexible painting processes.
  • solvent-based and water-based paints have been used to date for the coating of plastics.
  • Solvent-based UV dual cure systems have also been used for a number of years. They enable good matting properties as well as metallic colors. However, not all metallic colors can be produced with UV lacquers. High-gloss surfaces are created with solvent-based UV dual cure clear coats in a structure with base coats. Recently, both 100% UV clear lacquers with a piano lacquer look and 2K dual cure systems have been increasingly used for plastic lacquering, with the former having significantly higher chemical resistance properties.

They are used to produce coatings, in particular clearcoats and multicoat color and / or effect paint systems. Curing with actinic radiation is mainly carried out with UV radiation.
  • the binder components contained usually have different functional groups which, under suitable conditions, usually network independently of each other.
  • Customary dual cure systems belonging to the prior art have radiation-curable and thermally curable groups, with particularly advantageous properties being achieved when isocyanate and hydroxyl groups are used as thermally crosslinking functions.
  • EP 1 419 015 discloses a process for producing coatings from coating materials curable thermally and with actinic radiation, in which A) the coating materials are applied to primed or unprimed substrates or to uncured, partially cured and / or fully cured paint layers located thereon, and B) the resulting layers are applied the coating materials alone or together with the uncured and / or partially cured paint layers cures thermally and with actinic radiation, the Curing with actinic radiation is carried out under an oxygen-depleted atmosphere.
