Abstract
A thermal control coating composition comprising a binder made of a condensation polymerization product of Si--(OR).sub.4 added with titanium oxide acting as a white pigment, common mica particles for improving resistance to thermal cycling and cerium oxide particles for improving the resistance to UV irradiation. The thermal control coating composition has an initial solar absorptance (.alpha..sub.s) of not more than 0.3 and an initial thermal emittance (.epsilon.) of not less than 0.8. The coating composition exhibits excellent properties when subjected to an ageing test corresponding to the use thereof on a standstill orbit for 10 years. The weight of the paint may be reduced by the use of the coating composition of the invention such that an antenna (having a diameter of 3.5 m) of a large capacity communications satellite is coated with 3 kg of the coating composition of the invention to form a durable coating comparable to a coating formed by using 6 kg of a conventional thermal control paint.
