Gold, Copper and silver metal coating in far infrared region, the wavelength selection of much more than 4 mu m, a high reflectivity. As for the typical metal coating thickness, complete reflectivity of around 90%-ninety five%, high infrared reflectivity is such as very low emission level (Very low-e), this would https://3dprintingmaterials26936.blogoxo.com/35743745/getting-my-concrete-release-agents-to-work
