Abstract: A multicolor paint composition includes a continuous phase having a first rheology modifier and an optional second rheology modifier, a first discontinuous phase dispersed in the continuous phase, and a second discontinuous phase immiscibly dispersed in the continuous phase. The first discontinuous phase includes a first colorant having a first colorant strength, and an emulsion of a non-thixotropic polymer. The second discontinuous phase includes a second colorant having a second colorant strength, a third rheology modifier, and an emulsion of a first thixotropic polymer.

Abstract: A nozzle sand and method of use and operation, utilizes as a constituent component a granulated material that will break down to lose structural integrity and strength when subjected to temperatures and weight of molten ferrous materials, to compact to form at least a partial barrier to penetration of the molten ferrous material while remaining at least substantially in a granulated state. When the nozzle is opened, the loose nozzle sand will freely flow from the nozzle and the barrier will break under the weight of the ferrous material, such that the ferrous material will flow from the vessel through the nozzle. As a representative formulation, the nozzle sand can include between about 50 percent and about 60 percent by weight raw dolomitic lime; between about 20 percent and about 30 percent by weight forsterite; and between about 15 percent and about 20 percent by weight tabular alumina.

Abstract: A spray system for formulating an ambient curable clear coat product includes a first container containing a mixture of a polymer with primary hydroxyl functionality and an amino crosslinker with alkoxymethyl functionality and a propellant and a second container containing a catalyst formulated to initiate a polymerization reaction of the polymer and crosslinker when added to the first container. The system also includes a charging device configured to transfer the catalyst from the second container to the first container.

Abstract: An indicator is useful for detecting pressure points on a denture. The indicator is made of a composition that easily adheres to oral mucosa, has a proper viscosity in an oral cavity environment, can be properly spread between an oral mucosa surface and a denture base, and easily specifies an affected part. The composition includes a fatty acid ester having a melting point of 30 to 50° C., a water-soluble high polymer, and a metal oxide. Preferably, the fatty acid is 40 to 95% by weight of the composition, the water-soluble high polymer is 1 to 59% by weight of the composition, and the metal oxide is 0.1 to 50% by weight of the composition.

Abstract: The present invention relates to a substantially anhydrous suspension incorporating at least one biostable hydroxyalkylcellulose having an MS of 1.0 to 3.0, at least one oil, and at least one defoamer. The cellulose ether is preferably a hydroxyethylcellulose (HEC) having an MS of 1.0 to 3.0, preferably of 1.8 to 2.8, more preferably about 2.4. The oil is preferably a natural oil. Further disclosed is an emulsion paint, more particularly for interior coatings, which includes this suspension. It is particularly resistant to enzymes having a cellulytic action (cellulases), and this is manifested in a reduced fall in viscosity.

Abstract: A binder system for use in the formation of ceramic or other powder-formed greenware comprising a binder, a solvent for the binder, a surfactant, and a component that is non-solvent with respect to the binder and solvent. The non-solvent component exhibits a lower viscosity than the solvent when containing the binder and comprises a low molecular weight oil having a 90% recovered distillation temperature range of between about 220 to 400° C. Also disclosed is a process of forming and shaping plasticized powder mixtures and a process for forming ceramic articles utilizing the binder system.
