Abstract

A method for applying a water-based coating and/or coating system to a metallic substrate to form sag resistant coatings is described. The method is particularly effective for protecting metal-containing substrates, such as intermodal cargo containers, against corrosion. The water-based coating includes an aqueous carrier, a resin component in admixture with the aqueous carrier and a high level of one or more CAS agents for excellent sag resistance.
