Spectrally selective paint coatings were prepared by spraying method using polyurethane modified by acrylic resin as binder and CuCoMnOx semiconductive compound oxide as pigment. The effect of P/B (pigment/binder) ratio, milling time, temperature, substrates and film thickness on the optical properties of the coatings was investigated. The results show that the solar absorptance (αs) and thermal emittance (εT) of the coatings are 0.936 and 0.312 , the αs/εT ratio is 3.0 when the P/B ratio is 3:1, the milling time is 9～12h, the substrate is Al and the thickness is 1.9μm. The coating also has favorable mechanical behavior, corrosion resistance and weatherability.
