Abstract

a. L'invention concerne des produits de revêtement pulvérulents stables au stockage ayant une granulométrie inferieure à 0,25 mm et allant de préférence de 0, 2 à 0,06 mm. b. Ces produits sont caractérisés en ce qu'ils sont constitués par des mélanges finement divisés de composés 1,2-époxydes ayant plus d'un groupe époxy dans la molécule et un point de fusion inférieur > 40 degrés C et de durcisseurs hétérocycliques de formule générale :at. The invention relates to storage stable powder coating products having a particle size of less than 0.25 mm and preferably ranging from 0.2 to 0.06 mm. b. These products are characterized in that they consist of finely divided mixtures of 1,2-epoxy compounds having more than one epoxy group in the molecule and a lower melting point> 40 degrees C and heterocyclic hardeners of general formula :
