  • Publication number: 20230027538
    Abstract: Certain example embodiments of this invention relate to heat treatable painted glass substrates that have less than 11 wt. % (more preferably 5.40 wt. %, and still more preferably 5-9 wt. %) organic content in an as-deposited state, and/or methods of making the same. The paint preferably is curable at a temperature less than 300 degrees C. over a relatively short amount of time (e.g., less than 10-15 minutes), and the cured coated article may be stored for lengthy periods of time before being further processed.

  • Patent number: 11560331
    Abstract: A coated glass substrate and a method of making the glass substrate is disclosed. The method comprises the following: providing a coating formulation on a glass substrate wherein the coating formulation comprises at least one polymerizable compound, a glass frit, and a non-crosslinked polymer and heating the coating formulation on the glass substrate. The coated glass substrate includes a coating provided on a surface of a glass substrate wherein the coating comprises a semi-interpenetrating polymer network including a non-crosslinked polymer and a glass frit. The coating exhibits a stud pull of about 275 psi or more.

  • Patent number: 11112538
    Abstract: A first coating is provided on a first side of a glass substrate, and a second coating is provided on a second side of the glass substrate, directly or indirectly. The coatings are designed to reduce color change of the overall coated article, from the perspective of a viewer, upon heat treatment (e.g., thermal tempering and/or heat strengthening) and/or to have respective reflective coloration that substantially compensates for each other. For instance, from the perspective of a viewer of the coated article, the first coating may experience a positive a* color value shift due to heat treatment (HT), while the second coating experiences a negative a* color shift due to the HT. Thus, from the perspective of the viewer, color change due to HT (e.g., thermal tempering) can be reduced or minimized, so that non-heat-treated versions and heat treated versions of the coated article appear similar to the viewer.

  • Patent number: 11059740
    Abstract: A glass article comprising a glass substrate and a coating on a surface of the glass substrate is disclosed. The coating comprises a glass frit and a binder comprising an interpenetrating polymer network. The interpenetrating polymer network comprises a crosslinked polyol resin, a second crosslinked resin, and a third resin. A method of forming the glass article containing the coating is also disclosed.

  • Publication number: 20150064479
    Abstract: Certain example embodiments of this invention relate to heat treatable painted glass substrates that have less than 11 wt. % (more preferably 5-10 wt. %, and still more preferably 5-9 wt. %) organic content in an as-deposited state, and/or methods of making the same. The paint preferably is curable at a temperature less than 300 degrees C. over a relatively short amount of time (e.g., less than 10-15 minutes), and the cured coated article may be stored for lengthy periods of time before being further processed. In certain example embodiments, the coated article undergoes a significant color change upon heat treatment.
