Abstract: A coating composition is substantially free from chromate and comprises a resin, a metal salt, and an interference pigment. The interference pigment includes mica which has a solar reflective coating disposed thereon. A reflective coating system comprises a cured film formed from the coating composition disposed on a substrate. The cured film has a transparency of at least 75%, as measured according to ASTM 1746. In addition, the cured film has a solar reflectivity of at least 55%, as measured according to ASTM E 1918 and ASTM E 903. The cured film has excellent corrosion resistance properties and adhesion to the substrate.

Abstract: A method of maintaining a color of a cured film formed from a coating composition on a metal substrate relative to a standard comprises the steps of providing a resin, providing a pigment, combining the pigment and the resin to form the coating composition, applying the coating composition to the metal substrate, curing the coating composition to form the cured film having a color defined by an L value, an a value, and a b value, and maintaining the color relative to the standard having an Ls value, an as value, and a bs value whereby the L value, the a value, and the b value each change less than 20% respectively as compared to the L5 value, the as value, and the bs value of the standard. The cured film has a solar reflectance of greater than or equal to 0.75 in the wavelength from 250-2,500 nm.
