Abstract:
1. A method of fabricating an electrically insulating substrate painted with powder paint, said method comprising the following steps performed in succession: a) forming a treatment coating on a mold, the treatment coating comprising first and second preparation layers each based on an unmolding agent, the treatment coating formed by placing the first preparation layer on the mold, then polymerizing the first preparation layer and then covering the first preparation layer with the second preparation layer, with at least one of the first and second preparation layers including an electrically conductive element; b) electrostatically covering the treatment coating with powder paint in such a manner that the powder paint is attracted to the mold and is held against the treatment coating; c) transforming the powder paint at least in part in order to obtain a sheet of powder paint; and d) preparing the electrically insulating substrate on the sheet of powder paint to form the electrically insulating substrate painted with powder paint.
