  • Patent number: 8936745
    Abstract: The present invention relates to a method of fabricating a painted substrate (30) using powder paint (21), said substrate being electrically insulating, during which method the following steps are performed in succession: a) a treatment coating (10) is placed on a mold (1), said treatment coating (10) including at least one preparation layer (11, 12) based on an unmolding agent (15, 15?) in contact with said mold (1); b) said treatment coating (10) is electrostatically covered with powder paint (21) in such a manner that said powder paint (21) is attracted towards said mold (1) and is held against the treatment coating (10); c) said powder paint (21) is transformed at least in part in order to obtain a sheet (20) of powder paint (21); and d) said substrate (30) is prepared on said sheet (20) in order to obtain said painted substrate.

  • Patent number: 8563078
    Abstract: The present invention relates to a method of fabricating a painted substrate (30) using powder paint (21). The substrate is electrically insulating. The method includes the following steps performed in succession: a) a treatment coating (10) is placed on a mold (1), the treatment coating (10) includes at least one preparation layer having a release agent (15, 15?) in contact with the mold (1); b) the treatment coating (10) is electrostatically covered with powder paint (21) in such a manner that the powder paint (21) is attracted towards the mold (1) and is held against the treatment coating (10); c) the powder paint (21) is transformed at least in part in order to obtain a layer (20) of powder paint (21); and d) the substrate (30) is prepared on the layer (20) of powder paint to form the painted substrate.
