摘要: The present invention provides a method for sealing pinholes in an electroless metal coating, said comprising: (a) coating substrate with layer to provide coated article comprising contact the surface of substrate, being characterized by presence pinhole imperfections which allow fluid communication between and environment; (b) applying curable epoxy sealant over filling imperfections; (c) curing cured overcoating layer; (d) removing substantial portion is substantially free allowing environment.
