ABSTRACT:
The invention provides a rust inhibiting technology for zinc-coated and uncoated steel which insures at least the equivalent of results obtainable by the technology using a Cr-containing coating composition.
This method comprises coating a zinc-coated or uncoated steel substrate with a water-based resin composition comprising a carboxylated polyolefin resin and 70-0 part by weight of solid matter of at least one member selected from the group consisting of polyurethane resin, polyester resin, acrylic resin, epoxy resin, and alkyd resin as supplemented with 0.01-0.5 part by weight of phosphate ion based on 100 parts by weight of total solid matter of said water-based resin composition and adjusted to a pH value of not less than 7, either followed by heating the coated substrate at 50.degree.-250.degree. C. to dry the coat or preceded by heating said steel substrate at 50.degree.-250.degree. C. to let the then-applied coat dry spontaneously.
