Abstract
Abstract A composition suitable for producing a metal oxide coating on the surface of a heated refractory substrate is disclosed. The composition comprises a metal beta diketonate dissolved in a nonflammable, high-boiling, halocarbon-containing solvent mixture. The solvent mixture has surprisingly high solubility for transition metal beta diketonates. Because of the nonflammability and high-boiling characteristics of the solvent mixture, the composition is particularly useful for coating freshly formed float glass.
