Abstract: Disclosed are wax emulsion modifiers for concrete and cement formulations and methods for preparing the same. The modifiers are applicable to roller compacted concrete (RCC), used for manufacturing of industrial floor slabs, dams and roads. This invention also relates to conventional Portland cement concrete mix designs or other applied concrete mixes for formed structural shapes and transport road mix designs, providing a more rapid dehydration of the aqueous phase, without sacrificing strength, yet providing a higher density that remains workable at the point of application. The modifier of the invention may be utilized for either the initial soil/cement base or for the final/finished placement.

Abstract: Emulsions are provided which are useful in imparting water-resistance to lignocellulosic composite products. In one embodiment, the emulsions comprise at least one wax, an alkyl phenol, a salt of polynaphthalenesulfonic acid, and a complexed starch. Emulsions of this embodiment may be added to hot, even boiling, water without the emulsion separating or curdling. The emulsions of the present invention are stable for extended periods of time when stored at room temperature, do not require the addition of a bactericide, and are pourable liquids at room temperature.

Abstract: Emulsions, useful for imparting water resistance to gypsum products are disclosed. The emulsions of the invention include at least one wax, an alkyl phenol and a hydrophyllic metallic salt, preferably magnesium sulfate. The emulsions of the invention do not require the addition of a starch compound and therefore exhibit enhanced stability even at higher solids content then compared to prior art emulsions.

Abstract: The present invention relates to water-resistant gypsum compositions, methods of making such composition, as well as manufacturing methods and products comprising such compositions.

Abstract: The present invention provides a wax emulsion having thixotropic properties comprising a wax; an emulsifier, and a naphthenic oil.

Abstract: An aromatic solvent together with methods for its preparation are described. A composition includes a paraffin fraction in an amount of from approximately 9 LV % to approximately 15 LV %; a naphthene fraction in an amount of from approximately 35 LV % to approximately 55 LV %; and an alkylbenzene fraction in an amount of from approximately 8 LV % to approximately 16 LV %. The solvent provides advantages in that the high solvency that is typical of an aromatic solvent is combined with a narrow distillation range, a high flash point and higher boiling range that is typical of an aliphatic solvent.

Abstract: A metalworking lubricant composition which is effective as both a corrosion inhibitor and drawing lubricant and comprises a mineral oil and an additive combination of barium lanolate soap and barium sulfonate.
