Methods of changing the visible light transmittance of coated articles and coated articles made thereby |
摘要 |
A method is provided for changing the visible light transmittance of a coated article having a functional coating having at least one anti-reflective material and at least one infrared reflective material. The anti-reflective material includes an alloying material capable of combining or alloying with the infrared reflective material. A protective coating is deposited over the functional coating to prevent or retard the diffusion of atmospheric gas and/or vapor into the functional coating. The coated article is heated to a temperature sufficient to cause at least some of the alloying material to combine with at least some of the infrared reflective material to form a substance having a different visible light transmittance than the infrared reflective material. |

1. A laminated article, comprising:
a first ply having a first major surface; a functional coating over at least a portion of the first major surface and having an emissivity value; a protective coating comprising 35 wt. % to 100 wt. % alumina and 0 wt. % to 65 wt. % silica over at least a portion of the functional coating to form a coating stack having an emissivity, the protective coating configured to increase the emissivity of the coating stack over the emissivity of the functional coating alone; a second ply; and an interlayer located between the first and second plies, with the protective coating facing the interlayer. |
