Tungsten Oxide Applied for Car Heat Insulation Glass Coating

Tungsten oxide may be used to prepare car heat insulation glass coating. Specifically, some experts have obtained high transparent heat-insulating glass coating with good thermal insulation effect and excellent performance to resist ultraviolet by the following steps:

Weigh 82g of nano WO3 aqueous solution, 75g of nano ITO ethanol solution, 15g of modified silicone resin, 331g of n-butanol, 497g of deionized water, add to the container, and stir evenly to obtain heat-insulating coating of nano particle size tungsten oxide. The prepared heat-insulating coating is applied to the glass windows of the automobiles, and then the optical properties of the coated windows are tested according to the usual methods. The optical properties of the car windows applying with tungsten oxide heat insulation glass coating are shown as below: The visible light transmittance is 84.9%. The near-infrared transmittance is 43.4%. And the ultraviolet shielding rate is 97.9%. So, it is believed that such thermal insulation coating will be more and more widely applied in cars.
