  • Publication number: 20140261087
    Abstract: The present invention relates to light color, shelf-stable liquid compositions of overbased calcium carboxylate soaps and a process for their preparation. The inventive soaps are prepared by neutralizing calcium base in a mixture of two different aliphatic carboxylic acids and carbonating the mixture in the presence of a non-polar hydrocarbon solvent and a polar organic solvent as a promoter under controlled temperature conditions. The overbased calcium carboxylate soaps of the invention contain 20%-90% by weight of C7 to C25 saturated carboxylic acids, which are branched on carbon 2, and between 1% and 20% by weight short chain saturated carboxylic acids. These liquid compositions have light colors and excellent heat stability. They can be used as anticorrosion/antirust additives, and paint dryers and stabilizers, in paints, coatings and lubricants, as well as other applications.

  • Publication number: 20140275369
    Abstract: The present invention is directed to ready to use (wet) and setting (dry) repair products with antistatic additives having reduced persistent airborne dust particulates upon sanding thereof. Such wet and dry repair products include, in part, an antistatic additive(s) that can reduce or eliminate the static charge that forms in dust particulates when dried repair products, such as spackling compounds, cementitious materials, and joint compounds, are sanded, for example. In turn, this can help reduce the quantity of airborne dust particulates, the time in which they are suspended, and the distance they travel in a given room or job site. In one example, a repair product for use as a dry repair compound can include an anti-static additive, which can include a cationic charge, and optionally a metal complex. In another example, the repair product further includes water to define a wet or ready to use repair product.

  • Patent number: 8382950
    Abstract: The invention provides a method of recovering and recycling waste coating color from papermaking coating process for use as wet end filler. The inventive method overcomes many technical challenges inherent in using waste coating colors as wet end filler such as the coatings having fine pigments that hurts sheet strength more than regular filler, having strong anionic charge and tendency to disturb wet end chemistry, causing excessive foaming, and containing a large amount of hydrophobic binder particles that tend to agglomerate in the white water and deposit on papermaking equipment. The method involves mixing the coatings with fresh filler particles, adding de-foaming agent, adding cationic coagulant, then preflocculating the mixture. This process causes fresh filler particles, pigments and binders in waste coating color to agglomerate together and form stable flocs with defined particle size distribution.

  • Patent number: 7303623
    Abstract: A lime pellet for use in asphalt applications can include lime fines and an asphalt-compatible binder. The pellet is characterized as having a rigid structure with a dimension greater than about 1.5 mm and being compatible with a hot mix asphalt so as to dissolve in liquid asphalt. Optionally, the binder is characterized by having less than about 50% by weight of total binder being sulfur, or the pellet is characterized by having lime in an amount of at least 31% by weight, or being storage-stable and agglomeration resistant. The pellet is manufactured by mixing the lime fines with the asphalt-compatible binder and forming pellets therefrom. The pellets are useful for conditioning an end product of hot mix asphalt during the manufacture of such an asphalt. The method of conditioning includes providing the lime pellet, and mixing the lime pellet with a hot mix asphalt ingredient, wherein the ingredient is at least one of an aggregate or asphalt cement.
