METHOD OF MAINTAINING A COLOR OF A CURED FILM FORMED FROM A COATING COMPOSITION

摘要

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.
