Abstract
The invention embraces a formulation to be combined with a resin and a hardener to produce a paint mixture useful for coating concrete and metal surfaces, such as aluminum, zinc, stainless steel, and steel. With the inventive formulation, the pot-life of the paint mixture may be extended to up to about eight hours, allowing for a much greater time period during which the paint, after mixing, can be applied to a surface being coated. The formulation comprises a mixture of a defoamer; titanium dioxide (TiO.sub.2); at least one of barite (BaSO.sub.4) or calcite (CaCO.sub.3); at least one of 1,2-propyleneglycol (propane-1,2-diol), a corrosive-inhibitor, such as L-4, and a retarder such as LOXANOL.TM.; and a thickener. Other contemplated ingredients include slate, water, colorants, and dispersing additives.
