Violet tungsten oxide nanopowder may be applied for manufacturing a new type of glass thermal insulation coating for smart glass, in which nano violet tungsten oxide is used as a dingal powder, and a water-based hydroxy acrylic acid and an amino resin as a film-forming substance. The coating can be coated on glass and baked at 170°C-180°C. And the obtained film has high hardness, high adhesion, excellent water resistance, acid resistance and alcohol resistance. And the building glass will have a visible light transmittance of over 70% and near-infrared shielding rate of over 90%.

In the hot summer, glass doors and glass windows of common buildings will cause excessive consumption of indoor refrigeration appliances. In the cold winter, these glass doors and glass windows will increase the power consumption of indoor heating equipment. It means that you have to spend more money on electricity. In this regard, experts said that the new type of environmentally friendly heat insulation glass coating of violet tungsten oxide nano particles may be sprayed on the architectural glass. And the formed coating film can not only play the role of thermal insulation in hot summer and heat preservation in cold winter, but also can save unnecessary power consumption.
