Abstract
A cured coating composition and substrate coated with the cured coating composition which coating is based upon an aqueous acid binder solution containing phosphate and chromate and/or molybdate ions into which has been dispersed a blend of metallic powder particles of three primary dimensions and flat metal flake materials, which can be applied to a substrate part to be coated more uniformly and thickly than conventional metal flake coatings, and which imparts better corrosion and impact resistance than conventional powder metal coatings.
