Polyurethane power coatings nanocomposite samples. materials used for the exterior surface is mostly decorative elements, but they play an important role in control-ling the absorption of solar radiation16. There reflectance properties of metal oxide nanoparticles in the infrared region (NIR) were studied by Jee-vanandam and his co-works17.
Results indicated that, in the wavelength of solar radiation (infrared region), the average emissivity of coatings is about 0.87. Results showed that by adding modified nano ZrO2 and Al2O3 to polyurethane coatings, the emis-sivity coeficient of coatings compare to coating without nanoparticles increased.
