METHOD OF IMPARTING CORROSION RESISTANCE TO A SUBSTRATE COATED WITH A POWDER COATING COMPOSITION

摘要

The present invention is directed to a method for coating a substrate with a variety of coating compositions thereby imparting corrosion resistance properties to the substrate. In some embodiments, the method comprises: (a) depositing a pretreatment coating composition, which comprises zirconium, onto at least a portion of a substrate; (b) depositing a powder coating composition onto at least a portion of the pretreatment coating composition; and (c) curing at least a portion of the powder coating composition.
