Abstract: A coated electronic assembly comprises an electronic assembly, and a single-layer conformal coating overlying at least a portion of the electronic assembly. The conformal coating has a volume electrical resistivity of from about 108 to about 1014 ohm-centimeter. The conformal coating is formed of an organic polymeric binder, and a plurality of electrically semiconductive metal oxide filler particles dispersed in the binder. The binder and the filler particles have substantially the same visible-light refractive index. The binder may be a heat-curable or UV-curable urethane, and the particles may be doped (Al,Mg,Zn)3O4 or doped ZnO.

Abstract: A spacecraft has internal structure which generates heat, and a radiator element in thermal communication with the spacecraft internal structure. The radiator element has a radiating surface and a coating on the radiating surface including a white thermal control paint. The paint has an initial solar absorptance of not greater than 0.16 and an initial infrared emittance of not less than about 0.80. The standard end-of-life projected solar absorptance is not more than about 0.33 for a paint with an inorganic binder, and the standard end-of-life projected solar absorptance is not more than about 0.6 for a paint with an organic binder.

The radiator element has a radiating surface and a coating on the radiating surface including a white thermal control paint. The paint has an initial solar absorptance of not greater than about 0.20 and an initial infrared emittance of not less than about 0.80. The standard end-of-life projected solar absorptance is not more than about 0.3 for a paint with an inorganic binder, and the standard end-of-life projected solar absorptance is not more than about 0.6 for a paint with an organic binder.
