  • Patent number: 6855753
    Abstract: Disclosed is an acoustical tile composition in which the conventional starch binder is replaced by a wet-strength resin, such as a polyamine epichlorohydrin resin, can be fabricated into ceiling tiles and panels using conventional water felting processes and equipment with improved efficiency. The acoustical tile compositions, with the polyamine epichlorohydrin resins binder, can be dried significantly faster than comparable compositions containing conventional starch binders.

  • Patent number: 6509392
    Abstract: No-bake foundry binders that produce foundry shapes with improved hot strength are provided. The binder comprises a polyether polyol component, a polyisocyanate component and a catalyst component that promotes the trimerization of polyisocyanates to polyisocyanurates. Supplemental catalysts that promote the reaction of the isocyanate with the polyols may also be used. Foundry mixes are prepared by mixing the binder with a foundry aggregate and making foundry shapes using the no-bake process.

  • Patent number: 6010596
    Abstract: An improved water resistant gypsum board is made by adding an aqueous wax emulsion containing a cationic surfactant to an aqueous slurry containing calcium sulfate and host particles at a slurry temperature which maintains calcium sulfate hemihydrate crystals. The wax emulsion is stable at the temperature of slurry which maintains the calcium sulfate hemihydrate. The slurry is then dewatered and rehydrated to form a gypsum board and dried at a temperature to melt the wax.

  • Patent number: 5911818
    Abstract: A composition suitable for making acoustical tiles in a water-felting process comprises expanded perlite, clay, a binder component selected from the group consisting of starch, latex, cellulosic fiber and mixtures thereof and optionally mineral wool. The use of an expanded perlite having a relatively high density, preferably between about 9 pounds per cubic foot to about 20 pounds per cubic foot, enables the formation of a suitable slurry with a relatively low amount of water and enables a more complete dewatering of the mat prior to drying.
