摘要： A powder primer composition comprising as essential components (A) a carboxyl group-containing thermosetting polyester resin, (B1) a bisphenol A-type epoxy resin with an epoxy equivalent of 400-2000 g/eq or (B2) a bisphenol-type epoxy resin with an epoxy equivalent of 400-2000 g/eq and (C1) a bisphenol F-type epoxy resin with an epoxy equivalent of 400-2000 g/eq or (C2) a modified epoxy resin containing phenolic hydroxyl groups, obtained by reacting (a) a bifunctional epoxy resin with (b) an excess of a bifunctional phenol. Coating films obtained using the powder primer composition have excellent finished appearance and corrosion resistance.
