Abstract : The patent concerns a formulation providing coatings having high solar absorptance to infrared emittance ratios comprises oxidized copper flakes, a polymeric binder and a solvent for the binder. The oxidized copper flakes may be prepared by heating in an oxygen containing atmosphere prior to the inclusion in the coating formulation. The formulation is particularly useful for coating surfaces of missile and spacecraft structures where thermal balance is of prime importance. In general, the coated surfaces have a solar absorptance to infrared emittance ratio ranging from 1.80 to 2.60.
