Abstract
An article is coated with a mixture of a high absorptance pigment, a low absorptance pigment, a low emittance material, and a high emittance binder. Each of the components of the coating are stable when exposed to a space environment. The amounts of the high absorptance pigment and the low absorptance pigment are selected to produce an absorptance of the coating of from about 0.20 to about 0.90, and the amount of the low emittance material is selected to produce an emittance of the coating of from about 0.25 to about 0.90. The low absorptance pigment is preferably a white pigment such as zinc oxide. The high absorptance pigment is preferably a black pigment such as cupric oxide, cobalt oxide, or manganese dioxide. The low emittance material is preferably a metal such as aluminum. The binder is preferably a ceramic such as potassium silicate.
