Yellow tungsten oxide may be used to prepare a glass curtain wall heat insulation coating that can shield near-infrared rays and ultraviolet rays. Such transparent heat-insulating nano coating adopts an advanced production process to form tungsten nano particles and TiO2 into nano coating materials, which is suitable for coating on the surface of glass, ceramic tile, metal, cement, PE, PET, PC, PP, and PVC, etc.

Specifically, the transparent heat-insulating coating of tungsten trioxide nano particles can effectively shield 99% of ultraviolet rays, and can pass more than 75% of visible light, and can also block 92.5% of infrared rays. In addition, as the tungsten oxide nanoparticles can prevent excessive water vapor from entering, allowing a normal amount of water molecules to pass through, thereby the sun protection ability of the entire building surface can be greatly increased. It is reported that this new type of environmentally friendly coating meets the industry standard of "Thermal Insulation Coatings for Building Glass" and the national standard of "Thermal Insulation Painted Glass".
