Abstract
Coating compositions comprising aluminum pigment, neoprene latex asphalt emulsion, at least one surfactant for reducing reaction of the aluminum pigment with water and with the neoprene latex, at least one organic solvent, and water. The compositions are formed by providing an aluminum pigment mixture comprising aluminum pigment, the surfactant and the organic solvent, providing an aqueous neoprene latex asphalt emulsion and mixing the pigment mixture and the aqueous neoprene latex asphalt emulsion to form the coating composition. The compositions are suitable for coating a variety of surfaces, particularly roof structures and the like.
