Abstract
An aqueous ambient dry paint coating based on vinyl acetate matrix polymer containing a chlorinated hydrocarbon modifier selected from a chlorinated hydrocarbon having a Tg below -20.degree. C. and a number average molecular weight between 150 and 5,000, where the coating is free of organic coalescing solvents as well as other volatile organic compounds (VOC). The matrix polymer is produced by mixing the chlorinated modifier with the vinyl acetate monomer and other ethylenic monomers, if any, to form an organic mixture, providing an aqueous micro dispersion of the organic mixture phase having droplet size less than 5 microns, and copolymerizing the monomer to produce a polymeric binder of vinyl acetate polymer containing chlorinated modifier, where the polymeric binder system and coating is free of coalescing organic solvent.
