The transparent glass heat-insulating coating of nano WO3 particles can withstand temperatures from -50°C to 150°C. The coating layer is bright, transparent and heat-insulating with lasting and stable performance. And the hardness of the coating film can reach about 6H, which is wear-resistant with durability. Also, the coating itself is not flammable with certain flame retardant property. In addition, such coating also has the characteristics of good sealing performance, acid resistance, alkali resistance, corrosion resistance, aging resistance, high temperature resistance, cold resistance and shock resistance, so it can be used outdoors.
