Abstract
A method of making a coated substrate includes providing a substrate having at least one functional coating with a first emissivity value; depositing at least one coating material having a second emissivity value over at least a portion of the at least one functional coating wherein the deposited coating has a thickness ranging from greater than 100 Å to less than 10 microns and a refractive index ranging from 1.4 to 2. The resulting coating stack has an emissivity value greater than the emissivity value of the functional coating. Optionally the coated substrate is heated whereby the coated substrate can be bent to a desired shape and/or tempered.
Claims66
A method of making a coated substrate, comprising:
- providing a substrate having at least one functional coating with a first emissivity value;
- and
- depositing at least one coating material having a second emissivity value over at least a portion of the functional coating to provide a coating stack having an emissivity value greater than the emissivity value of the functional coating, wherein the thickness of the deposited coating material has a thickness of greater than 100 Angstroms and less than 10 microns and has a refractive index in the range of 1.4 to about 2.
A method of making a laminated article, comprising the steps of:
- providing a first substrate having a major surface;
- applying a functional coating having an emissivity value over at least a portion of the first substrate major surface;
- applying a protective coating over at least a portion of the functional coating to form a coating stack having an emissivity value greater than the emissivity value of the functional coating;
- providing a second substrate;
- heating the first and second substrates to desired shapes;
- and
- laminating the first and second substrates together with an interlayer, with the protective coating facing the interlayer.
A method of making a coated article, comprising the steps of:
- providing a coating having a predetermined solar infrared reflectance and a predetermined thermal emissivity;
- and
- altering the coating such that the thermal emissivity increases but the solar infrared reflectance remains substantially the same.
A laminated article, comprising:
- a first ply having a first major surface;
- a functional coating deposited over at least a portion of the first major surface and having an emissivity value;
- a protective coating deposited 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.
An article, comprising:
- a substrate;
- a functional coating deposited over at least a portion of the substrate;
- and
- a protective coating deposited over the functional coating, wherein the functional coating and the protective coating define a coating stack and the protective coating provides the coating stack with an emissivity higher than the emissivity of the functional coating alone wherein the thickness of the protective coating has a thickness of greater than 100 Angstroms and less than 10 microns and has a refractive index in the range of about 1.4 to about 1.8.
39 The article as claimed in claim 24, wherein the protective coating comprises 86 wt. % to 90 wt. % alumina and 10 wt. % to 14 wt. % silica.
A monolithic transparency, comprising:
- a glass substrate;
- a functional coating deposited over at least a portion of the glass substrate;
- and
- a protective coating deposited over the functional coating to form a coating stack, the protective coating comprising aluminum oxide having a thickness in the range of 1 micron to 10 microns and providing the coating stack.
A method of making a coated substrate, comprising:
- providing a substrate having at least one solar infrared reflective dielectric coating ;
- and
- depositing a coating material so that the deposited coating material has a thickness of greater than 100 Angstroms and less than 10 microns and has a refractive index in the range of about 1.4 to about 1.8.
An article, comprising:
- a substrate;
- at least one solar infrared reflective dielectric functional coating deposited over at least a portion of the substrate;
- and
- a protective coating deposited over the functional coating, wherein the protective coating has a thickness of greater than 100 Angstroms and less than 10 microns and has a refractive index in the range of 1.4 to about 2.
