Abstract

The invention relates to a high temperature curable coating composition comprising: (a) at least one film-forming resin, (b) at least one crosslinker for the film-forming resin, wherein the crosslinker is not substantially reactive at temperatures under 120° C., and (c) an anticorrosive agent, which comprises a combination of a magnesium compound and a water-soluble Li salt. The invention further provides a method of coating a metal substrate and a coated metal substrate. The resulting coating has excellent anticorrosive properties without the use of Cr(VI) compounds, while being suitable for high temperature cure conditions typical in coil coatings.
