摘要： Coating compositions having a polymeric binder and a stabilizer composition including at least one of a UV absorber, a hindered amine light stabilizer (HALS), or an inorganic UV blocker are provided herein, wherein said coating compositions are more resistant to discoloration when exposed to UV-C (190-280 nm) light compared to the coating compositions in the absence of the stabilizer composition. Thus, a method of stabilizing a coating composition against the deleterious effects of UV-C (190-280 nm) light includes adding to the coating composition an effective amount of such a stabilizer composition, wherein the coating composition is made more resistant to discoloration when exposed to UV-C (190-280 nm) light compared to the coating composition in the absence of the stabilizer composition. Coated articles can be made from the coating composition, and methods of making stabilized coating films include adding the stabilizer composition to the coating composition.

摘要： Bauxite grinding compositions that can significantly reduce the viscosity of bauxite slurry, which allow alumina refinery plants to increase throughput of bauxite grinding or pre-desilication. Described are processes to improve the grinding of a bauxite containing slurry in a Bayer process comprising: adding an effective amount of a bauxite grinding composition to the bauxite containing slurry before or during the grinding step or pre-desilication step, wherein the bauxite grinding composition comprises dextran, maltitol or a co-polymer.

摘要： Polymer compositions for making stabilized polymeric articles that are resistant to at least one deleterious effect of discoloration, cracking, or crazing upon exposure to UV-C (190-280 nm) light are provided herein, wherein the polymer compositions include: (i) an organic polymeric material; and (ii) a stabilizer composition comprising: an antioxidant selected from the group consisting of hindered phenols, phosphites and phosphonites, and mixtures thereof; and a light stabilizer selected from the group consisting of hindered amine light stabilizers (HALS), UV absorbers (UVA), hindered benzoates, and mixtures thereof, even where barium compounds (such as barium salts) are absent from the stabilizer composition, and with the proviso that the HALS is not bis(2,2,6,6,-tetramethyl-4-piperidyl) sebacate (TINUVIN™ 770) alone. At least one of reduced discoloration, cracking, or crazing upon exposure to UV-C light is associated with the use of the light stabilizer in combination with the antioxidant compared to the antioxidant in the absence of the light stabilizer. Methods of stabilizing organic polymeric materials against the deleterious effects of UV-C light by adding to the organic polymeric materials the antioxidant and the light stabilizer, are also provided.

摘要： Agglomerated products formed from particulate materials and binder formulations having low molecular weight polymers (of 500 g/mol to 50,000 g/mol) in an aqueous or emulsion form, or having a blend of low molecular weight aqueous polymer and high molecular weight (of 500,000 g/mol to 50,000,000 g/mol) emulsion polymers, wherein the polymers are formed from water soluble ethylenically unsaturated monomers, or monomer blends, chosen from one or more of acrylic acid, acrylamide, maleic acid, allyl sulfonate, silanated and/or hydroxamated acrylamide, or 2-acrylamido-2-methylpropane sulfonic acid (AMPS), are disclosed herein as well as processes for agglomerating a particulate materials, and use of the binding agents for forming same.
