Abstract

L'invention concerne une peinture pulvérulente à base de résines époxy et de durcisseurs phénoliques, s'utilisant notamment pour le revêtement intérieur de récipients d'emballage, qui contient 1) au moins une résine époxy d'un poids équivalent en époxy compris entre 300 et 5500 et au moins un durcisseur comportant plus d'un groupe hydroxyle phénolique par molécule et un poids équivalent en hydroxyle compris entre 100 et 500, par rapport aux groupes OH phénoliques; la peinture pulvérulente présentant une répartition granulométrique telle a) qu'au moins 90 % en poids des particules de peinture pulvérulente présentent une dimension particulaire comprise entre 1 et 60 µm, b) que la dimension particulaire maximale des particules de peinture pulvérulente soit <= 100 µm pour au moins 99 % en poids des particules, c) que la dimension particulaire moyenne des particules de peinture pulvérulente soit comprise entre 5 et 20 µm et d) que la pente de la courbe de répartition granulométrique soit >= 100 au point d'inflexion et 2) un lubrifiant, de préférence dans un volume <= 2 %.
