    Abstract: A waterborne coating composition includes latex particles and a crosslinker. The latex particles can be prepared from a mixture of reactants including: (a) a monomer represented by formula (I): where R1 is a hydrogen or methyl group and R2 is a hydrogen, alkyl, or aryl group; (b) a multi-ethylenically unsaturated monomer; and (c) a mono-ethylenically unsaturated functional monomer different from in the monomer represented by formula (I), the mono-ethylenically unsaturated functional monomer having a functional group selected from a hydroxyl group, thiol group, group, or a mixture thereof, where R9 is a hydrogen, alkyl, or aryl group. A method of preparing waterborne coating compositions and substrates coated with the compositions are also disclosed.

    Abstract: Blended fluoropolymer compositions are provided. In one embodiment, a liquid dispersion of a first fluoropolymer is blended with a liquid dispersion of a second fluoropolymer. The first fluoropolymer may be polytetrafluoroethylene (PTFE), such as a low molecular weight PTFE (LPTFE) that has been polymerized via a dispersion or emulsion polymerization process, and which has not been agglomerated, irradiated, or thermally degraded. The LPTFE may be in the form of an aqueous dispersion, having a mean particle size of less than 1.0 microns (m), with the LPTFE having a first melt temperature (Tm) of 332° C. or less. The second fluoropolymer may be a melt processible fluoropolymer (MPF), such as methylfluoroalkoxy (MFA), fluorinated ethylene propylene (FEP), or perfluoroalkoxy (PFA), for example, in the form of an aqueous dispersion, and having a mean particle size of less than 1.0 microns (m). Blending of the dispersions facilitates interaction of the LPTFE and MPF on a submicron level to facilitate intimate blending such that, when the blended fluoropolymer composition is dried, a crystal structure representing a true alloy of the fluoropolymers is formed, having melt characteristics that differ from those of the individual fluoropolymers. The blended fluoropolymer composition may be used to provide a coating having improved impermeability, stain resistance, abrasion resistance, smoothness, and higher contact angles.

    Abstract: The present invention relates to new acrylic associative thickening agents which, when polymerized in the presence of particular polyglycerols, ultimately result in an increase of the open time of the paint or of the thick coating in which they are incorporated. By so doing, painters and applicators will have more time to work the paint layers gradually or to correct imperfections such as paint droplets, traces of brushes and filling-knives.
