Abstract
A zinc-stable ceramic ink composition which contains a metal oxide, a glass frit, a UV-curable vehicle, zinc powder, and a calcium-containing organic complex. The calcium-containing organic complex prevents premature polymerization of the UV-curable vehicle so that the zinc-containing ink composition may be stored for extended periods of time prior to use.
Claims20
A ceramic ink composition comprising a metal oxide, a glass frit, a UV-curable vehicle, zinc powder, and a calcium-containing organic complex.
A ceramic ink composition comprising from about 8 to 25 percent by weight of a metal oxide, from about 30 to 50 percent by weight of a glass frit, from about 20 to 35 percent by weight of a UV-curable vehicle, from about 5 to 55 percent by weight of zinc powder, and from about 0.2 to 8.0 percent by weight of a calcium-containing organic complex.
A two-part ceramic ink composition wherein the first part comprises an acrylate oligomer and wherein the second part comprises zinc powder, a calcium-containing organic complex, and a reactive diluent selected from the group consisting of tripropylene glycol diacrylate, polyethylene glycol diacrylate, 2-(2-ethoxy-ethoxy)ethyl acrylate, trimethylol propane propoxylate triacrylate, and mixtures thereof;
- and wherein a metal oxide, a glass frit, and a photoinitiator are contained in either or both of the two parts.
