RUVA-93 by Otsuka Chemical is 2-Propenoic acid 2-methyl-, 2-[3-(2H-benzotriazol-2-yl)-4-hydroxyphenyl]ethyl ester. It is a reactive ultraviolet stabilizer. It is used in plastic lenses, film, sheets, packaging material, containers, fiber, and as alternative plastic to glass. It is a reactive ultraviolet absorber that is able to copolymerize efficiently with a variety of vinyl monomers such as methacrylic, styrenic, and acrylonitrile monomers. Provides permanent placement of the benzotriazole in the polymer. Imparts high weatherability to thin films and fibers. Provides permanence of the stabilizer in the resin and improved compatibility even in very high loadings. RUVA-93 offers excellent environmental acceptability, expanded technology options, and the ability to design new UV polymer screens with unique properties.

Luna-nox MD 1024 is recommended for the stabilization of polymers in contact with copper both during processing and long term service. It combines both an antioxidant and a metal deactivating function for outstanding protection in a variety of polymers for applications like wire, cables, hoses and composites.

Luna-fos 126 is a high performance organophosphie processing stabilizer which protects coatings from thermo-oxidative degradation by decomposing hydroperoxides to form non-radical, non-reactive products.

Luna-stab LS-144 is a hindered amine light stabiliser (HALS) that signifiantly coating life by minimising paint defects such as cracking and gloss reduction.
