Abstract

L'invention concerne une peinture en poudre, notamment pour le revêtement intérieur de contenants d'emballage, caractérisée en ce que 1) elle contient au moins une résine à fonction polyhydroxy avec un indice d'hydroxyle compris entre 5 et 200 mg KOH/g et au moins un durcisseur de polyisocyanate avec au moins un groupe isocyanate par molécule et en ce que 2) elle présente une répartition granulométrique telle qu'au moins 90 % en masse des particules de peinture en poudre possèdent une dimension de particule comprise entre 1 et 60 µm, que la dimension maximale des particules de peinture en poudre est inférieure ou égale à 100 µm, que la dimension moyenne de particules de peinture en poudre est comprise entre 5 et 20 µm et que la pente de la courbe de répartition granulométrique est supérieure ou égale à 100 au point d'inflexion.
