Abstract

A rust-preventing or rust-removing composition consists of a water-insoluble binding material which dries in the air, a rust or metaldissolving acid and an organic acid or salt or derivative thereof. The metal salt formed by the action of the metal-dissolving acid forms with the organic acid an insoluble precipitate which adheres to the metal. In examples, phosphoric or a volatile acid such as formic acid is mixed with tannic, gallic, pyrogallic, benzoic or nucleic acid and the mixture incorporated in cellulose or other varnish. Small amounts of stannous or stannic chloride may be added as catalysts together with inert pigments such as titanium white, heavy spar, graphite or soot.ALSO:A rust-preventing or rust-removing composition consists of a water-insoluble binding material which dries in the air, an acid which will dissolve the rust or the metal, and an organic acid or a salt or derivative thereof. The metal salt formed by the solution of the rust or the metal reacts with the organic acid to form an insoluble precipitate which adheres to the metal. For example, phosphoric acid or a volatile acid such as formic acid is mixed with tannic, gallic, pyrogallic, benzoic, or nucleic acid and the mixture incorporated in cellulose or other varnish, a precipitate of iron tannate, iron benzoate, iron nucleinate &c. being formed by the reaction of the composition with the clean or rusty iron. Small amounts of stannous or stannic chloride may be added as catalysts, together with inert pigments such as titanium white, heavy opar, graphite, or soot.
