  • Patent number: 10793740
    Abstract: The invention relates to an aqueous dispersion of a polymer P, which comprises the emulsion polymerization of vinyl acetate, an acrylate monomer, which is a C1-C10 alkyl acrylate or a C1-C10 methacrylate, an ?,?-ethylenically unsaturated C3-C8 carboxylic acid and at least one out of glycidyl methacrylate, glycidyl acrylate, allyl methacrylate and allyl acrylate, in the presence of a starch derivative. Optionally, an additional monomer is an ethylenically unsaturated sulfonic acid, an ethylenically unsaturated other monomer or both of them. The aqueous polymer dispersion and a powder form thereof are useful for a paper coating slip containing one of the aforementioned forms. A paper or a cardboard, which is coated with the paper coating slip, shows surface strength, which is expressed by a good dry pick resistance, a good wet pick resistance or good offset test results. The aqueous polymer dispersion or the powder form thereof is furthermore useful as a binder.

  • Patent number: 10358387
    Abstract: A refractory composition is formed by preparing a set retarded fresh cementitious composition formed from a class C fly ash, a set retardant such as boric acid, and an alkali activator such as an alkali metal citrate salt, and contacting the set-retarded fresh cementitious composition with a pH regulator, such as an alkali metal hydroxide or alkali metal carbonate. The set retarded mixture provides workability and avoids equipment fouling caused by premature setting, while the alkali activator provides rapid setting when desired. The cementitious composition is shaped into a brick, panel, slab, concrete fire log, or the like and allowed to harden. The hardened cementitious composition can be heated to form a dried cementitious composition, and further heated to produce a high strength refractory composition. Fibers and/or aggregates may be included.

  • Patent number: 7267782
    Abstract: A two-part sizing composition including a precursor size composition and a binder composition, the binder composition being substantially free of any aminosilane coupling agent for is provided for the production of reinforcing fiber materials that exhibit little or no coloration. The two-part sizing composition may be advantageously employed to make substantially colorless, densified fiber pellets of a reinforcing fiber material. The densified fiber pellets may be produced by applying the sizing composition to reinforcing fiber strands, chopping the reinforcing fiber strands to form chopped strand segments, applying the binder composition, and palletizing and densifying the coated chopped strand segments to form flowable densified fiber pellets.

  • Patent number: 7169463
    Abstract: An aqueous glass fiber sizing composition that includes a polymeric film forming component, at least one silane coupling agent, and one or more lubricants is provided. The polymeric film forming component of the sizing composition includes a silanated polyvinyl acetate, an epoxidized polyvinyl acetate, and a modified epoxy emulsion. In preferred embodiments, the film formers are present in the sizing composition in ratios of 70:25:5, 50:25:25, or 63:18:18 of silanated polyvinyl acetate, epoxidized polyvinyl acetate, and modified epoxy emulsion respectively. Fibers sized with the sizing composition in a sheet molding compound process have improved wet-out characteristics.

  • Patent number: 7083855
    Abstract: A binder slurry for a continuous filament mat used in a phenolic pultrusion system comprising a phenolic compatible silane, a non-ionic surfactant, a defoamer, water, an organic acid and a bisphenol epoxy powdered resin having a thermally active dicyandiamide cross-linking resin. The binder slurry resin is unique in that the bisphenol epoxy powdered resin having a thermally active dicyandiamide cross-linking resin is compatable with presently available phenolic resins, and as such pultruded parts made have improved surface and mechanical properties as compared with traditional polyester type binder slurries which are not compatable with phenolic resins. Continuous filament mats made with the new binder slurry also may also be made into epoxy prepreg that can be used to make composite parts.
