Appl. No.:

12/844865

Inventors:

Jonathan T. Stuart - Lansdale PA, US
Ariel Lender - Schwenksville PA, US

Assignee:

Henry Company LLC - El Segundo CA

International Classification:

C08K 3/34
F16L 9/14

US Classification:

524493, 138145

Abstract:

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.

Assignee:

Henry Company - El Segundo CA

International Classification:

C04B 24/26

US Classification:

524 5

Abstract:

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.
