  • Publication number: 20210087408
    Abstract: Water-based coating compositions or paint having improved gloss retention, including a latex or water-dispersible polymer, a UV-VIS absorber comprising a substituted benzophenone capable of being a free radical generator, a hindered amine light stabilizer, and optionally a low-VOC coalescent provided in a preferably desired amount. A composition comprising a blend a UV-VIS absorber comprising a substituted benzophenone capable of being a free radical generator, a hindered amine light stabilizer, and a low-VOC coalescent, providing a thermally-stable coalescent that can be used in a paint formulation for gloss retention. Gloss retention of paints containing the UV-VIS absorber and hindered amine light stabilizer being markedly improved over paints that do not have both components present.

  • Patent number: 10851213
    Abstract: A method for optimizing a Hegman rating of a diluted emulsion including adjusting the shear work in the dilution mixer, wherein the adjusting the shear work may comprise raising or lowering the shear work; adjusting the temperature of the concentrated and/or diluted emulsion; if not earlier added, adding a basic aqueous solution and/or dispersing agent; adding one or more other additives; and/or adjusting the amount of any additive, basic solution or surfactant solution is provided. Also provided are diluted emulsions produced thereby and coatings made from the diluted emulsions.

  • Publication number: 20140256860
    Abstract: The present disclosure provides for an aqueous solvent-free short oil alkyd resin dispersion and a process for producing the same. The aqueous solvent-free short oil alkyd resin dispersion, according to the present disclosure comprises from 35 to 65 percent by weight of a short oil alkyd resin based on the total weight of the dispersion, where the short oil alkyd resin has a weight average molecular weight (Mw) in the range of 5,000 to 5,000,000 Dalton and a volume average particle size diameter in the range of 0.05 to 1.0 ?m; 0.1 to 6 percent by weight of a surfactant, based on the total weight of the dispersion; and 29 to 65 percent by weight of water, based on the total weight of the dispersion, where the aqueous solvent-free short oil alkyd resin dispersion does not include a solvent.

  • Publication number: 20140221561
    Abstract: An alkyd surfactant which is effective in emulsifying alkyd resins is formed by copolymerization of at least one monomer having a hydrophilic group, at least one ethylenically unsaturated fatty acid or ester, and optionally, at least one polyol, and has a low degree of branching. Stable alkyd emulsions are formed by emulsification of alkyd resins with the alkyd surfactant. Since the alkyd surfactant has ethylenically unsaturated hydrophobe groups which can react with the alkyd resin during curing, the alkyd surfactant is not subject to migration, blooming or leaching from cured coatings.
