BRONZE COLORED HEAT TREATABLE COATED ARTICLE HAVING LOW SOLAR FACTOR VALUE Russian patent published in 2018 - IPC C03C17/36 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to a glass coated with a bronze color. Coated article comprises a glass on which the layers are applied in the following sequence as they move away from the glass: a first dielectric layer containing silicon nitride; the first infrared reflecting layer containing NbZr; a second dielectric layer containing silicon nitride; a second IR-reflective layer containing NbZr; third dielectric layer containing silicon nitride. Coated product has a visible reflection coefficient on the glass side of not more than 15 %. Coated product has a bronze reflection on the outside / glass side, including the color value a* on the glass side / from -2.0 to +16.0 outside and the color value b* on the glass side / outside from 0 to +20. When measured on a single glass, the coated product has a solar factor (SF) value of not more than 0.31 and the coefficient of heat inflow from solar radiation (HISR) is not more than 0.36 and / or for a heat insulating double-glazed window with two glass substrates has a SF value of not more than 0.22 and a value of HISR not more than 0.25.

EFFECT: providing a product with a bronze color with a low solar factor and / or a low coefficient of heat input from solar radiation.
