Abstract

L'invention concerne une matière de recouvrement s'utilisant dans un processus d'impression électrostatique avec des particules de matériau. Selon l'invention, pour obtenir des revêtements superficiels présentant une surface de haute qualité, notamment une bonne résistance à l'abrasion sur pratiquement n'importe quel type de matériau, il est prévu qu'au moins une partie des particules du matériau comporte des constituants duromères à base de résine et d'un durcisseur. L'invention concerne en outre un procédé de fabrication d'une matière de recouvrement de ce type.
