Abstract The space environmental and technical performances of the organic silicone antistatic white thermal control coatings were studied. The effects of combined irradiation with UV, electrons and protons, and with the UV and atomic oxygen on the change of solar absorptivity (αs) were studied in a space environment simulation facility. The experimental results show that the white thermal control coating is highly stable in the low-orbit space environment. It was found that after combined irradiation by 5000 ESH of UV, total electron doses of 2.0 × 1014 e/cm2 and total proton doses of 5.0 × 1012 p/cm2; combined irradiation by 5000 ESH of UV and atomic oxygen with a fluence 5.0 × 1021 atoms/cm2 simultaneously, the solar absorptivity of these coatings changed very little. The effects of coating thickness on solar absorptivity and adhesion strength between the coatings and substrates were analyzed. The thermal cycling performances of the coatings on different kinds of substrates under temperature variation from −196 to +150 °C were investigated.
