    Abstract: 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.

    Abstract: Processes for inhibiting scale produced during wet process phosphoric acid production by adding a scale-inhibiting amount of a reagent having a primary amine-containing polymer, or salt thereof, to one or more stages of a wet process phosphoric acid production stream are provided herein, wherein the primary amine-containing polymer includes an A mer according to Formula (I): where R is H, C1-C6 alkyl, C2-C6 alkenyl, halide, or carboxyl; R1 is H, C1-C6 alkyl, or C2-C6 alkenyl; R2 is H or an A mer according to Formula (I) as herein defined; R3 is chosen from a direct bond or a C1-C12 alkyl, C2-C12 alkenyl, or a C6-C12 aryl group; and n is an integer chosen to provide a weight average molecular weight of the primary amine-containing polymer of at least 300 Daltons, and wherein the percentage of primary amines in the polymer is from 30 mole % to 100 mole % based on the total percentage of mer units in the polymer.
