COPPER CONDUCTOR COMPOSITION FOR PORCELAIN ENAMEL STEEL SUBSTRATES

摘要

A thick film conductor composition is disclosed. The composition consists essentially of an admixture of finely divided particles of 65 to 80 parts by weight copper metal powder, 1.5 to 6 parts by weight copper oxide, and 3 to 8 parts by weight low melting temperature glass frit which sinters at 550.degree. to 700.degree.C dispersed in an organic vehicle comprising 20% to 40% by weight methacrylate resin dissolved in a volatile solvent. The thick film conductor composition is adapted for use with porcelain enamel steel.
