  • Patent number: 10435938
    Abstract: A vacuum insulated glass (VIG) window assembly and method for making same is provided in which a variation in the final edge seal height is preferably 0.20 mm or less, more preferably about 0.15 mm or less. Controlling final edge seal height variations substantially reduces breakage of the glass substrates of the VIG window assembly during vacuum pump-down of the cavity between the glass substrates. Edge seal height variation may be controlled, for example, by controlling initial dispensing of green frit material, controlling temperature variations during firing, and/or controlling cycle times during firing.

  • Patent number: 10329187
    Abstract: Certain example embodiments relate to seals for glass articles. Certain example embodiments relate to a composition used for sealing an insulted glass unit. In certain example embodiments the composition includes vanadium oxide, barium oxide, zinc oxide, and at least one additional additive. For instance, another additive that is a different metal oxide or different metal chloride may be provided. In certain example embodiments, a composition may be combined with a binder solution that substantially or completely burns out by the time the composition is melted. In certain example embodiments, a CTE filler is included with a frit material. In certain example embodiments, a vacuum insulated glass unit includes first and second glass substrates that are sealed together with a seal that includes the above-described composition.

  • Patent number: 10267085
    Abstract: A vacuum insulated glass (VIG) window assembly and method for making same is provided in which dimensions of a hole formed in a glass substrate in which a pump-out tube is to be inserted is selected such that it provides sufficient clearance for efficient insertion and accommodates sufficient adhesive material (e.g., frit inclusive paste), while at the same time providing sufficient support to resist substantial tilting or tipping of the pump-out tube when inserted in the hole. In addition, a length of the pump-out tube is selected so that a distance between a top of the pump-out tube (which is later subjected to heat sealing, e.g.

  • Publication number: 20180328026
    Abstract: Some embodiments include an exterior insulated finish wall assembly including an exterior panel member and an insert member. The exterior panel member includes a rigid insulative substrate and a base coat selectively disposed on the rigid insulative substrate. The rigid insulative substrate includes a body portion and a tail portion extending from the body portion. The body portion has a first thickness and the tail portion having a second thickness less than the first thickness. The tail portion defines a recessed portion extending along a length of a lower edge. The insert member is configured to be disposed in the recessed portion. The insert member is sized and shaped to correspond to the recessed portion. The insert member includes the rigid insulative substrate and the base coat selectively disposed on the rigid insulative substrate. A drainage channel is defined between the tail portion and the insert member when assembled.

  • Publication number: 20160347650
    Abstract: Certain example embodiments of this invention relate to a frit slurry paste for use in assemblies (e.g., a vacuum insulated glass unit or a plasma display panel), and methods of making the same. Frit powder, binder material, and a water-based solvent are mixed together to form an intermediate mixture. The frit powder is substantially lead free, and the water-based solvent is provided at a first temperature. Additional water-based solvent is added to the intermediate mixture to form a frit slurry paste. The additional water-based solvent is provided at a second temperature, with the second temperature being lower than the first temperature. The binder material is provided at a concentration of 0.001%-20% by weight with respect to the frit slurry paste or the frit slurry paste absent the frit powder. The frit slurry paste has a bulk viscosity of 2,000-200,000 cps.
