The effects of electron flux on the optical properties of ZnO/K2SiO3 thermal control coating are studied. Th e test specimens were exposed to electrons at a flux of 5×1011/cm2·s，8×1011/cm2·s，1×1012/cm2·s and 5×1012/cm2·s, respectively . The irradiation caused an optical degradation of the coatings. And an air bleaching phenomenon of the degraded coatings was observed. Mechanisms for optical degradation of ZnO/K2SiO3 thermal control coating are analyzed. The influence of electron flux on solar absorptance is also discussed. It is found that in the electron flux range of 5×1011 to 1×1012/cm2·s, there are no different electron flux effects on the optical properties of ZnO/K2SiO3 thermal control coating. Accordingly, in this range the accelerated ground-based testing to simulate e
