Abstract

Procedure for the preparation of a varnish in powder form that provides polishable coatings based on an epoxy resin in solid powder form at 50ºC, a combination of an insufficient amount for the total hardening of a hardening agent more reactive for the epoxy resin and of a quantity sufficient for the final hardening of a less reactive hardening agent for the epoxy resin, pigments and possibly other usual additive substances excluding usual fillers as well as corrosion inhibiting substances, characterized in that the epoxy resin and the remaining components are plasticized at a temperature above the melting point of the resin, above the temperature of entry into action of the most reactive hardening agent and below the temperature of entry into action of the least reactive hardening agent, are homogenized, and they are transformed so per se known in powder varnishes.
