Tungsten trioxide may be used to prepare a new type of glass curtain wall heat insulation coating with high heat insulation and high UV resistance. If you are focused upon glass heat insulation coatings, you may know that the "Quality Evaluation Standard for Glass Insulation Coatings" has been implemented on June 1, 2019.

In terms of content, the standard specifies the terms and definitions, classification and marking, requirements, test methods, inspection rules, marking, packaging, transportation and storage of glass thermal insulating coatings. The "standard" has improved and revised the key indicators in practical applications, and has clearly defined the products used on the glass of traffic vehicles. It has established a clear classification of quality for various products, to curb the phenomenon of “good and bad mixed together” of the glass heat insulation coating industry from the source. Among them, the thermal insulation temperature difference, ultraviolet transmittance, shielding coefficient retention rate, and equivalent conductivity K value are the highlights of this standard, laying a solid foundation for future related products to enter the market.
