Abstract: 323,525. Imray, O. Y., (I. G. Farbenindustrie Akt.-Ges.). Aug. 23, 1928. Coating-compositions.-Anti-corrosive coatings for metal particularly iron, surfaces comprise solutions in an organic solvent of a cellulose ether which is insoluble in water, e.g. benzyl-cellulose, and a heavy metal salt of an acid of high molecular weight, e.g. a higher fatty acid, naphthenic acid, resin acid &c. Suitable salts include copper naphthenate, copper oleate, lead naphthenate, ferric stearate, ferric laurate and ferric resinate. They are insoluble in water and render the coating waterproof. By selection of a suitable salt, e.g. a copper salt, the solutions are useful for coating ship's bottoms and other metal surfaces which are exposed to the attack of lower animal and vegetable organisms. Colouring matter, softening and filling agents may also be incorporated in the lacquer, and further coatings of a cellulose lacquer, linseed oil varnish or wood-tar oil may be applied. The cellulose ether coating may also be produced by means of a mixture of the cellulose ether solution and an oil. Examples of lacquers are (1) benzyl-cellulose dissolved in a mixture of benzene xylene and alcohol to which tricresyl phosphate and copper napthenate are added. The copper napthenate may be replaced by a napthenate of lead, iron, nickel or cobalt. (2) Benzyl-cellulose is dissolved in the above solvent mixture and tricresyl phosphate and ferric stearate are added. The ferric stearate may be replaced by ferric laurate, cupric laurate or ferric resinate.
