Series 22 colorant formulation from Ferro Corporation is said to prevent float and flocculation of pigments, increasing uniformity of coloration achieved using "4800 Epoxy Colorseal" from Versatile Building Products. Versatile Building Products Inc. (VBP) manufactures treatment and repair products for cement, concrete and stone floors. These range from epoxy and polyurethane coating systems for commercial and residential applications to stains, sealers, mortar and substrate repair materials.
One such product is the company's 4800 Epoxy Colorseal, a chemical- and abrasion-resistant topcoat for concrete floors specifically formulated to reduce or eliminate color variations associated with epoxy coatings. These variations, explains Mark Glendrange, VBP's technical director, are due to the "float and flocculation" of pigments that occurs in the coating following application, until the point of cure.
