  • LOW/ZERO VOC GLYCOL ETHER-ESTERS AS COALESCENTS FOR AQUEOUS POLYMERIC DISPERSIONS
    Publication number: 20120258249
    Abstract: Certain ether-esters compounds and certain ether ester coalescents are provided. Also provided are an aqueous coating composition including an aqueous polymeric dispersion and from 0.1% to 40% by weight, based on the weight of the aqueous polymeric dispersion solids, of the glycol ether-ester coalescents and a method for forming a coating from the aqueous coating composition.

  • Method for extending the open time of an aqueous coating composition
    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.
