ABSTRACT:
Method and composition utilizing organo substituted quaternary ammonium salts to effect the solution of hexavalent chromium into organic materials such as paints, in which such inhibitors are normally insoluble, in order to upgrade the corrosion protection properties of these materials. A quantity of organo substituted quaternary ammonium salt is dissolved in organic material. A quantity of simple alkali metal chromate or dichromate is then mixed with the resulting solution and is dissolved therein.
