Summary:The present invention relates to a novel, self-crosslinking powder coating material based on epoxy resins and to its use to coat shaped parts. A self-crosslinking powder coating material, comprising(A) up to 50% by weight, based on the powder coating material, of a mixture of(A1) at least one epoxy resin with an epoxy equivalent weight (EEW) <800 g,(A2) at least one epoxy resin with an epoxy equivalent weight (EEW) of from 800 to 1500 g, and(A3) at least one epoxy resin with an epoxy equivalent weight (EEW) >1500 g,and(B) at least 50% by weight, based on the powder coating material, of at least one filler;and its use to coat shaped parts, especially engine blocks, which after coating are shaped by machining.
