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 ...


1. A frit slurry paste, comprising: a water-based solvent;a bismuth- or ceramic-based frit powder, the frit powder being substantially free from lead; anda binder comprising methylcellulose at a concentration of 0.25%-5% by weight,wherein the frit slurry paste has a bulk viscosity of 2,000-200,000 cps, andwherein the frit slurry paste has annealing, softening, and working temperatures less than about 470 degrees C. with all lying within a range of about 120 degrees C. of each other. 2. The frit slurry paste of claim 1, wherein the binder is provided at a...
