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

Luna-nox 1076-J is a hindered phenol antioxidant, widely used in polymers including polypropylene, polyethylene, polystyrene, polyamide, ABS, and synthetic rubbers. It is also an effective antioxidant in oils and paints.

Luna-nox 1076-J is odourless, tasteless, low toxicity (LD50≥10000mg/kg) and light-stable, and is recommended for use at 0.1 – 0.3% dosage rate.
