These coatings are used primarily for work applied over copper when substrate integrity and longevity are desired but a specific color other than the naturally occurring copper hues is required.
Copper is an excellent substrate for a painted finish.
Prior to painting, the surface must be free of grease, oil, dirt, fingerprints, drawing compounds and surface passivation treatment chemicals. A first coat of an industrial wash primer should be applied according to the specific manufacturers recommendation. Appropriate finish coatings are industrial enamels and silicone alkyd enamels of the specified color. The lamination of very thin gold leaf to copper is a very old tradition. The physical advantages of gold's color and weatherability with copper's sub-surface integrity combine into a very durable, long lived, maintenance free surface.
