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.

  • Patent number: 5270380
    Abstract: A method for extending the open time of an aqueous coating composition is provided. This method extends the time during which an aqueous coating can be applied or rebrushed without damaging the film. The open time improvement of this invention is useful for a variety of coatings including paints, stains, varnishes, adhesives, and inks. The aqueous coating composition contains a latex polymer and a modifying compound. More particularly, the latex polymer contains a first reactable group which is complementary to and reacts with a second reactable group in the modifying compound. The complementary reactable groups in the latex polymer and modifying compound provide ionic or covalent binding.
