The invention relates to hardenable powder paints, which can be produced by applying at least one dispersion and/or at least one solution (I) containing: (A) at least one functional constituent of a powder paint; (B) at least one solvent and, optionally; (C) at least one oligomeric and/or polymeric constituent, to the surface of dimensionally stable particles (II) while partially removing the solvent or solvents (B) in an essentially complete manner or completely altogether. The invention also relates to a novel mixing system and to a novel method for producing and/or for subsequently adjusting the material composition and/or the application-technology property profile of hardenable powder paints, in which at least one dispersion and/or at least one solution (I) are/is used.
L'invention concerne une peinture pulvérulente durcissable, obtenue par application d'au moins une dispersion et/ou au moins une solution (I) contenant (A) au moins un constituant fonctionnel d'une peinture pulvérulente, (B) au moins un solvant, ainsi qu'éventuellement (C) au moins un constituant oligomère et/ou polymère, sur la surface de particules (II) aux dimensions stables, avec élimination partielle, sensiblement complète ou totale du solvant ou des solvants (B). L'invention concerne en outre un nouveau système mélangeur et un nouveau procédé permettant de produire et/ou d'ajuster ultérieurement la composition des substances et/ou d'ajuster le profil des propriétés techniques de peintures pulvérulentes durcissables, selon lequel au moins une dispersion et/ou au moins une solution (I) sont utilisées.
