Abstract

179,811. Howse, G. H. May 2, 1921. Paints and coating-compositions.-A coating- composition to be applied to steel and iron surfaces to prevent rust and to convert existing rust into an inert form comprises an axy-acid of phosphorous, an oxide or hydrate of chromium, and a solvent of these, with or without oxides, hydrates, or chromates of manganese, lead, or nickel. According to one example, a mixture of lead oxide and orthophosphoric acid is dissolved in a mixture of wood spirit, acetone, ethyl alcolhol, and methylated spirits, and a mixture of chromium oxide and phosphorous acid is added thereto. According to another example, chromic hydroxide is digested for 24 hours with boiled linseed oil or other drying oil, with or without heating, orthophosphoric acid is then added and the mixture is agitated. Pigments possessing rust-reducing properties may be added. The composition after drying may be covered with a coating of paint, varnish, enamel, or the like.
