Violet tungsten oxide for producing transparent heat insulation glass coating is violet tungsten oxide nano powder, which is a kind of nano functional material. And the building glass water-based transparent heat-insulating coating prepared from violet tungsten oxide nanoparticles has excellent optical properties – it can maximize the effects of shielding near-infrared rays and shielding ultraviolet rays on the basis of ensuring the visible light transmittance.

It should be noted that the choice of film-forming material has a great influence on the performance of the coating during the preparation of smart coating. So, how to choose a film-forming substance? What are the types of film-forming substances for preparing coatings? At present, the film-forming materials in architectural glass water-based transparent heat-insulating coatings should be selected to make the coating film have high transparency, good adhesion to the substrate, strong aging resistance and weather resistance, and certain chemical inertness. The more commonly used film-forming materials are water-based polyurethanes, water-based acrylic resins, water-based fluorocarbon resins, and the like.
