Abstract
A method for making a glass frit paste is provided. First, nitrocellulose is dissolved in a high vapor pressure solvent of the nitrocellulose to make a solution. A portion of the solution is then mixed with alpha-terpineol to form a vehicle. Glass frit is mixed with the vehicle and then ground to form the paste. During the grinding step most of the high vapor pressure solvent evaporates. The resulting paste has a composition comprising about 0.3-12.0 wt. % nitrocellulose, about 0.5-2.0 wt. % of a high vapor pressure solvent of said nitrocellulose, about 14.0-25.0 wt. % alpha-terpineol, and the remainder glass frit.
