Abstract
In this research, black silicate thermal control coatings were prepared with using two inorganic black pigments; copper oxide and iron oxide, in potassium silicate binder in three pigment to binder ratio then they were applied on aluminum substrate. The optical properties of coatings were measured by UV/vis spectrophotometer. Evaluation of the coatings general properties indicated that the adhesion of paint samples was equal to 5B. The bend and impact tests passed without any cracking and separating of coating from substrate and the coating weight loss after abrasion test was around three milligram. Evaluation of optical properties indicated that the coatings containing of copper oxide had lower absorptance than the coatings with iron oxide and later coatings were absorbed almost whole wavelengths from UV to VIS and pigment to binder ratio did not have significant effect on the coating absorptance. Its solar absorption and thermal emittance were 0.98 and 0.92 respectively.
