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.

Abstract: The invention relates to a non-intumescent, waterborne fire-retardant coating composition comprising: (a) at least one binder resin having reactive functional groups comprising both hydroxyl and carboxylic groups, wherein the binder resin has an acid value lower than 40 mg KOH/g resin on solids and an OH value higher than 30 mg KOH/g resin on solids, (b) a crosslinker, capable of reacting with at least some of the functional groups of the binder resin (a), wherein the crosslinker contains a carbodiimide functionality, and (c) at least one fire retardant. The resulting coating has a good adhesion to a variety of substrates, prolonged pot-life, and complies with the requirements of fire resistance in aircraft industry.
