Patent number: 9045370Abstract: Aqueous wax emulsions are disclosed herein for use in gypsum formulations and other building products which emulsions include water; a paraffinic hydrocarbon; a montan wax component; and a hydrocarbon component. Optional emulsion and strength additives may be included in the emulsion or in a slurry formed from such emulsion for preparing a settable gypsum composition herein. The hydrocarbon component is at least one hydrocarbon compound having from 5 to 20 carbon atoms or at least one hydrocarbon resin which is based on the at least one hydrocarbon compound as a monomer, wherein the resin is at least a dimer comprising the hydrocarbon compound and the resin has a molecular weight (Mw) of no greater than about 3,000, wherein the hydrocarbon compound is saturated or unsaturated, functionalized or nonfunctionalized and is aliphatic, alicyclic, or aromatic, wherein the hydrocarbon component has a softening point of from about 22° C. to about 110° C.Type: GrantFiled: October 20, 2011Date of Patent: June 2, 2015Assignee: Henry Company LLCInventors: Jonathan T.

Patent number: 8748515Abstract: 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.Type: GrantFiled: February 18, 2011Date of Patent: June 10, 2014Assignee: Henry Company LLCInventors: Jonathan T. Stuart, William J. Werts

Patent number: 8557909Abstract: 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 included 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.Type: GrantFiled: July 28, 2010Date of Patent: October 15, 2013Assignee: Henry Company LLCInventors: Jonathan T. Stuart, Ariel Lender

Publication number: 20120263963Abstract: Provided herein is 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 ?-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 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.Type: ApplicationFiled: April 17, 2012Publication date: October 18, 2012Applicant: Henry Company LLCInventors: Dennis Michael Mahoney, John Hartley Burns, Jonathan T.
