  • Publication number: 20240101750
    Abstract: Provided are antifog hydrophilic polyurethane compositions including: (a) from 20% to 70% by weight side-chain ethylene oxide monomeric units, based on the total weight of the polyurethane; (b) from 10% to 100% by weight of at least one main-chain polyol having a number-average molecular weight of from 200 to 900 g/mol, based on the total weight of main-chain polyols present in the polyurethane; and (c) an amount of acid-functional units effective to provide an acid number of from 1 to 100 mg KOH/g to the polyurethane. Methods of making and using such compositions are also provided.

  • Patent number: 11718763
    Abstract: Water-based stains are based on an oil-in-water emulsion having a binder that includes, consists of, or consists essentially of drying oil combined with a non-aqueous polymer dispersion. The compositions can be tinted using traditional water-based pigment dispersions, yet the overall hydrophobicity results in minimal interaction with the polar cellulosic structure of wood.
    Type: Grant

    Date of Patent: August 8, 2023
    Assignee: The Sherwin-Williams Company
    Inventor: Joshua Halstead
  • Publication number: 20220282108
    Abstract: A wood stain composition comprises or consists essentially of a water-miscible polyol having a molecular weight less than 1000 Da, a water-dispersible hydrophobic polymer and a pigment dispersion for providing improved application properties and compliance with regulatory VOC limits.

  • Patent number: 10519334
    Abstract: Water-based stains comprise or consist essentially of a polysaccharide resin and a crosslinking agent such as an isocyanate. Upon evaporation of water, the polysaccharide undergoes crosslinking with the isocyanate component, developing water resistance so that it will not redissolve upon application of a water-based or oil-based clearcoat; as a result, lifting is minimized after a drying time of, e.g., two to six hours.

  • Patent number: 10370541
    Abstract: An emulsion-based latex aerosol paint comprises 5-50 weight percent of one or more hydrocarbon solvents, 0.05-10 weight percent of a surfactants with a Hydrophilic-Lipophilic Balance value of 4-10, 10-70 weight percent of a water-based coating emulsified into a mixture of the one or more solvents and the one or more surfactants. The emulsion-based latex aerosol paint may be additionally charged with a hydrocarbon propellant at a level of 5 to 50 weight percent. The hydrocarbon propellant may be selected from propane, butane, isobutene and mixtures thereof.
