Gold, copper and silver metal coating in much infrared region, the wavelength choice of more than 4 mu m, a high reflectivity. As for The standard steel coating thickness, overall reflectivity of up to 90%-95%, high infrared reflectivity is reminiscent of small emission rate (Reduced-e), this would reduce the radiation https://rylanijigd.bloggadores.com/34701143/about-polypropen
