Tungsten oxide can be used for heat insulation coating. Tungsten oxide nano powder is a new type of thermal insulation material that reflects near-infrared rays. And this new type of heat insulation material is generally in the form of powder, paste or thin film to be coated or attached to the substrate of building materials. NIR Shielding Material – Tungsten Oxide/Solvent type Polyurethane Composite Film The tungsten oxide/solvent type polyurethane (WO3/PU) composite film may be prepared by coating method using…
