A method of making a thermal control coating is provided. A primer layer can be applied to a substrate to form an exposed surface. The primer layer can include an epoxy binder and a silica filler. The exposed surface can be treated with an oxygen plasma to form a treated surface. A silicate-based thermal control coating can be applied to the treated surface, for example, by spraying, to form a thermal control coating on the substrate. Spacecraft and spacecraft hardware components coated with the thermal control coating, are also provided.

The disclosure relates to a method for coating a substrate with a lacquer. First, the lacquer is uniformly applied to the substrate. Then, the solvent proportion of the lacquer applied to the substrate is reduced, and the coated substrate is exposed to a solvent atmosphere. In some embodiments, the lacquer is heated. The invention also relates to a device for planarising a lacquer layer.
