摘要:
A finished flake for a roofing material including a metal flake substrate having an emissivity value up to approximately 0.25 and a reflectivity value up to approximately 0.95. A first coating is provided having unpigmented sodium silicate disposed on the substrate, wherein the first coating increases the emissivity value of the substrate and decreases the reflectivity value of the substrate. A second coating is provided having sodium silicate loaded with reflective pigments non-uniformly disposed about the first coating, wherein the finished flake has an emissivity value in excess of approximately 0.75 and a reflectivity value ranging from approximately 0.4 to approximately 0.5.
