ABSTRACT:
Disclosed is an improved fast dry and extremely durable waterborne, coating composition particularly adapted for use as a traffic paint. The basic waterborne coating for traffic paint is comprised of an aqueous emulsion containing an acrylic film forming polymer, a stabilizing system for the emulsion which is pH sensitive, and mineral pigment. The improvement to the basic water borne coating for traffic paint resides in utilizing a hydrophobic acrylate containing polymer which incorporates from about 0.1 to 5% by weight of an secondary or tertiary amino acrylate and a crosslinkable monomer as components of the hydrophobic polymer. The hydrophobic acrylate containing polymer should contain less than 5 weight percent of hydrophilic monomers.
