Abstract (en)
[origin: DE19531585A1] The present invention concerns a powder coating based on epoxy resins and phenolic hardeners, in particular for the internal coating of packing containers, and containing: 1) at least one epoxy resin with an epoxide-equivalent weight of between 300 and 5500; and at least one hardener with more than one phenolic hydroxyl group per molecule and a hydroxyl-equivalent weight, relative to phenolic OH groups, of between 100 and 500; the powder coating having a grain size distribution such that: a) at least 90 mass % of the powder coating particles have a particle size of between 1 and 60 mu m; b) the maximum particle size of the powder coating particles for at least 99 mass % of the particles is </= 100 mu m; c) the average particle size of the powder coating particles is between 5 and 20 mu m; and d) the slope of the grain distribution curve at the inflection point is >/= 100; and 2) a lubricant, preferably in an amount of </= 2 wt.%.
