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.
Claims13
A method for dissolving an inorganic alkali metal salt in a liquid organic material comprising:
- dissolving an effective amount of an organo substituted quaternary ammonium salt in said liquid organic material to form a first solution;
- and
- mixing an effective amount of said inorganic alkali metal salt with said first solution to form a second solution including cations from said quaternary salt and anions from said inorganic alkali metal salt in said liquid organic material;
- wherein said alkali metal salt is selected from the group consisting of sodium chromate, sodium dichromate and potassium chromate.
A solution, comprising:
- a liquid organic material containing, in solution, cations from an organo substituted quaternary ammonium salt, and anions from an inorganic alkali metal salt selected from the group consisting of sodium chromate, sodium dichromate and potassium chromate.
