Abstract:

An improved preparation of a lusterless water-displacing paint is disclosed wherein solvents including ethyl acetate, aromatic mineral spirits and 1,1,1 trichloro-trifluoroethane are mixed in specific proportional amounts and a binder of silicone alkyd resin is completely dissolved therein. A small quantity of a titanate coupling agent is blended into the solution and milled along with selected amounts of pigments, including titanium dioxide and zinc molybdate, to a predetermined Hegman grind range. Thereafter, respective amounts of an anti- settling agent, preferably an extremely pure fumed silica, and a low molecular weight petroleum sulfonate are added and blended separately, each for about 30 minutes. Finally, a synthetic silica for flattening the finish of the paint coating is added and the resultant formulation milled to a fine Hegman grind.
