This paper discusses the development and evaluation of a highly adherent, low solar absorptance, porcelain enamel thermal control coating applied to 6061 and 1100 aluminium for space vehicle use. The coating consists of a low index of refraction, transparent host frit and a high volume fraction of titania as rutile, crystallzed in-situ, as the scattering medium. Solar absorptance is 0,21 at a coating thickness of 0,013 cm. Hemispherical emittance is 0,88. The change in solar absorptance is 0.03, as measured in-situ, after an exposure of 1000 equivalent sun hours in vacuum. (Kurzetz)
