Abstract
Certain example embodiments relate to heating a ceramic paint applied to a portion of a coated article in order to at least partially “eat through” the underlying coating, with any remaining materials being removable by washing, and associated articles. In certain example embodiments, the coatings are multilayer sputter-deposited coatings formed on a glass or other substrate. The heat may be provided in connection with conventional heat treatment (e.g., thermal tempering) and/or heat bending processes that otherwise would be performed on the coated article.
Claims9
A method of making a coated article including a sputter-deposited coating supported by a glass substrate, the method comprising:
- applying a coating-dissolving material comprising ceramic paint over and contacting the sputter-deposited coating in one or more areas in which the sputter-deposited coating is to be removed, wherein the ceramic paint comprises oxides of phosphorous and sodium;
- heating the glass substrate with the coating-dissolving material comprising ceramic paint applied over and contacting the sputter-deposited coating at a temperature of 580-650 degrees C. for no more than 10 minutes, the heating causing the sputter-deposited coating under the coating-dissolving material to be at least partially damaged in the one or more areas in which the sputter-deposited coating is to be removed but not causing undesired damage to the sputter-deposited coating in other areas;
- and
- following the heating, washing the glass substrate to remove excess material(s) from the glass substrate in the one or more areas in which the sputter-deposited coating is to be removed, in making the coated article,
- wherein the coating comprises a plurality of dielectric layers.
