ABSTRACT:
Epoxy-resin powder primer compositions for metal substrates which have good flow, corrosion resistance, and adhesion to lacquer overcoats are provided by blending two epichlorohydrin-bisphenol-A epoxy resins with a curing agent. One of the epoxy resins can be extended with phenol to increase its flow properties. The curing agent is a hydroxy-containing mixed aromatic-aliphatic polyether resin.
