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: Resin masterbatch compositions are provided as closed end pellets having a core including at least one additive and an outer layer comprising a polymer encapsulating the core, in which the thickness of the outer layer if from 0.001 mm to 1 cm. A stabilized composition is prepared from an organic material to be stabilized and the resin masterbatch composition. A process for producing the resin masterbatch composition includes co-extruding in tubular form a core material encapsulated by an outer layer, wherein the core material comprises at least one additive, and the outer layer comprises a polymer, to form a filled tube; passing the filled tube into a sealing device that cuts the filled tube into multiple discrete segments seals and simultaneously seals each end of each discrete segment, thereby forming closed end pellets; and cooling the closed end pellets.

Abstract: 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.
