| 20110257301 | Mixtures and Emulsions for Use in Providing Strength to Gypsum Compositions - Settable gypsum compositions are described herein which include a gypsum slurry, comprising water; and a first additive comprising a vinyl acetate/ethylene copolymer in latex or emulsion form and a second additive which is at least one of (i) a wetting agent and/or a surfactant; (ii) a titanium coupling agent, (iii) a zirconium coupling agent, and (iv) mixtures thereof. The compositions demonstrate improved strength and gypsum core adhesion. Such compositions may also include at least one dispersant and/or a wetting agent and/or a surfactant. Such dispersants may be lignosulfonic acid, naphthalene sulfonic acid, and combinations and salts thereof and the wetting agent and/or surfactant may be N-dodecyl 2-pyrrolidone, ethoxylated alcohol, and combinations thereof. The dispersant and/or wetting agents and/or surfactants can further enhance rheological properties to benefit the enhanced strength gypsum compositions. | 10-20-2011 |
| 20110048569 | Coating Composition Exhibiting Reduced Block, Rapid Dry Rate and Related Methods - An emulsion composition to coat a substrate that includes a barrier-forming material, water; an organometallic compound, and at least one thickener is described. The composition may further include a material such as talc. Articles, including ductile pipes, coated with this material are also described. A method of increasing the drying rate of a composition applied to a substrate to form a coating that includes application of the emulsion composition and drying the composition to form a coating layer. Also include are methods of forming a coating that exhibits a reduced incidence of blocking or pull-off, comprising applying the emulsion composition to a substrate and drying, whereby the coating layer formed exhibits a reduced incidence of blocking or pull off relative to conventional asphalt emulsion coatings. | 03-03-2011 |
| 20100116406 | Wax Emulsion for Use in Building Products - Provided herein are an aqueous wax emulsion, comprising water; a paraffinic hydrocarbon; polyvinyl alcohol and a wax component comprising synthetic olefin wax component. The synthetic olefin wax component may be selected from the group consisting of (i) a synthetic normal α-olefin wax; (ii) a synthetic olefin wax of a carbon chain length of about 20 or more carbon atoms, that is modified by oxidizing and/or by refining through distillation or stripping; and (iii) combinations thereof. Such emulsions are also useful for and disclosed herein are settable gypsum compositions and water-resistant wallboard formed therefrom. Also included herein is a montan wax substitute for use in an aqueous montan-based wax emulsion having paraffinic hydrocarbon, a wax component, water and polyvinyl alcohol wherein the wax component includes the montan wax substitute in place of use of a montan wax in the wax component such that the montan wax substitute is about 1 part to about 100 percent of the wax component and includes a synthetic olefin wax. | 05-13-2010 |
