PRODUCT WITH LOW-EMISSION COATING HAVING SYSTEM REFLECTING IR-RADIATION, INCLUDING BARRIER LAYER OR LAYERS BASED ON SILVER AND ZINC Russian patent published in 2021 - IPC C03C17/36 

FIELD: glazing.

SUBSTANCE: group of inventions relates to coated products intended for use in windows, for example in double-glazed window units, vehicle windows, monolithic windows and/or so forth. A coated product includes coating applied to glass substrate. Coating contains the first dielectric layer on glass substrate, the first barrier layer containing zinc, which is metallic or essentially metallic, an infrared (hereinafter – IR) reflecting layer containing silver, the second barrier layer containing zinc, which is metallic or essentially metallic, another barrier layer containing Ni and/or Cr, and the second dielectric layer on glass substrate. The first barrier layer is located on glass substrate above at least the first dielectric layer. The infrared (IR) reflecting layer is located on glass substrate above and in direct contact with at least the first barrier layer containing zinc. The second barrier layer containing zinc is located on glass substrate above and in direct contact with the IR-reflecting layer containing silver, so that the IR-reflecting layer containing silver is located between and in direct contact with the first and the second barrier layers containing zinc. The barrier layer containing Ni and/or Cr is located above and in direct contact with the second barrier layer containing zinc. The second dielectric layer is located above at least each of the mentioned first and second barrier layers, another barrier layer and the IR-reflecting layer. At the same time, coating has specific surface resistance (R_s) of no more than 11 Ohms/square and a normal emission coefficient (E_n) of no more than 0.2.

EFFECT: increase in chemical resistance and environmental resistance.
