PCT No. PCT/EP91/02024 Sec. 371 Date May 27, 1993 Sec. 102(e) Date May 27, 1993 PCT Filed Oct. 25, 1991 PCT Pub. No. WO92/09664 PCT Pub. Date Jun. 11, 1992.In order to obtain a two-component epoxy resin/zinc dust priming coat which for ecological reasons requires little or no solvent, the powdery or flaky zinc, reactive in water, is dispersed in a water-free, water emulsible epoxy resin binder (component A). Component A is mixed immediately before being applied with a water-diluted or water-dissolved polyamine hardener (component B).
