    摘要: The present invention is directed to a method for improving the adhesion of epoxy resins to steel substrates which comprises first removing the oxide surface layer, preferably by chemical means, and then pretreating the substrate with a solution of at least one coupling agent selected from the group consisting of .beta.-diketones and mercaptoesters. The invention also provides a method for improving the adhesion of epoxy resins to steel substrates by pretreating with citric acid or a salt thereof.
