摘要：

Black, green and mixed paints were prepared from organically modified siloxane resin. The solar absorptance (a(s)) of prepared black paint/metal coatings was 0.90 with corresponding thermal emittance (e(T)) 0.20, whereas green paint coatings did not reach satisfactory solar absorptance (a(s) < 0.80). To improve the absorptance of the green coating, the black paint was admired into the green paint. Optical properties of the prepared coatings were determined by the help of Kubelka-Munk formalism.
