Experts said that the tungsten trioxide heat insulating nanoparticles can effectively shield infrared radiation and ultraviolet radiation. The infrared shielding rate is 85%, and the ultraviolet shielding rate is 99%. That is attributed to the stable chemical properties of such thermal insulating nanoparticles, and the small physical changes caused by external environment such as heat and humidity. The energy efficient coating is mainly applied by spraying, and the obtained architectural glass coating material has excellent compatibility with the substrate, and has good spreading and leveling performance. Also, it will not fall off for a long time. In addition, the new environmentally-friendly and energy-saving coating has the advantages of good light transmittance, strong adhesion, high hardness, scratch resistance, water resistance, temperature resistance, and UV aging resistance.
