  • Patent number: 9593051
    Abstract: A method for making a coating composition by mixing one or more latex polymers and an aliphatic epoxy resin system having an epoxy equivalent weight less than 1000 and being distinct from the one or more latex polymers to provide an aqueous first component, and providing a second component having reactive groups that can react with the one or more epoxy resins. A mixture of the first and second components provides a film-forming curable coating composition that may be used on substrates including cement, cement fiberboard, wood, metal, plastic, ceramic, glass and composites.

  • Patent number: 9346905
    Abstract: A reaction mixture containing a copolymer having a number average molecular weight less than about 4,000 amu and a polydispersity less than about 3 formed in the presence of a free radical initiator and a heated liquid reaction mixture fed with one or more added olefinic monomers, the reaction mixture otherwise consisting essentially of non-homopolymerizable olefinic monomer.

  • Publication number: 20150105528
    Abstract: A copolymer is made by feeding one or more added olefinic monomers into a reaction vessel containing a non-homopolymerizable olefinic monomer heated to a temperature of at least about 100° C. The process may be performed in a batch or continuous fashion, may use an unpressurized reactor, may be performed without added solvent, and may form a copolymer whose number average molecular weight is less than about 4,000 amu and whose polydispersity is less than about 3.

  • Patent number: 8993110
    Abstract: A coated fiber cement article in the form of an unattached fiber cement board substrate having a first major surface at least a portion of which is covered with a crush resistant final topcoat composition comprising a multistage latex polymer, and a method for making a crush resistant coated fiber cement article by coating a fiber cement board substrate with such a composition and stacking the coated boards.

  • Patent number: 8932718
    Abstract: A coating system, a method of coating a substrate, and a coated substrate (e.g., a coated cement fiberboard article) include one or more latex polymers, an aliphatic epoxy resin system, optionally a silicate additive, and optionally one or more olefinic compounds and an initiator. The coating system may be applied in one or more layers and may be applied to all the surfaces of the substrate (e.g., the front side, back side and edges of a board). The coated substrate may then be coated with other optional coatings, e.g., decorative or protective topcoats.

  • Patent number: 8748550
    Abstract: A vinyl polymer pigment dispersing agent having a vinyl addition polymer backbone, one or more polymer side chains with pendant cyclic urea functional group(s) separated from the polymer backbone by at least 10 intervening atoms, and in some embodiments one or more polymer side chains comprising pendant urea functional groups separated from the polymer back-bone by less than 10 intervening atoms. The dispersing agent may be made by addition polymerizing a mixture of one or more vinyl monomers and one or more monomers having cyclic urea functional groups and vinyl functional groups. The dispersing agent may be combined with pigment particles, a carrier and an optional surfactant to make a pigment grind dispersion with excellent pigment wetting and dispersing properties.
