Its low basicity prevents possible interactions with acidic paint ingredients such as catalysts. Its efficiency provides significant improvement in coatings performance by minimizing paint defects such as cracking and gloss reduction for clear coats as well as chalking for pigmented paints. Decanedioic acid, ELV(2,2,6,6-tetramethyl-1-(octyloxy)-4-piperidinyl) ester, reaction products with 1,1-dimethylethylhydroperoxide and octane Average molecular weight: 737 CAS No. 129757-67-1 TINUVIN 123 is recommended for applications such as: · automotive and industrial coatings · decorative paints and wood stains or varnishes TINUVIN 123 has been developed especially for high solids, acid catalyzed automotive and industrial coatings, i.e. two coat metallic thermosetting acrylate systems or one coat opaque thermosetting acrylate and polyester coatings. Its high efficiency has been demonstrated in a variety of other binders and applications such as: · alkyd/acrylic air drying automotive refinish paints · alkyd oxidative drying paints and varnishes · two pack non-isocyanate coating technologies The liquid form of TINUVIN 123 also enables easy emulsification into water-borne systems. The performance of TINUVIN 123 can be significantly improved when used in combination with a UV absorber. In Automotive coatings, combinations of TINUVIN 123 with the UV absorbers TINUVIN 384, TINUVIN 1130, TINUVIN 928, or TINUVIN 400 will significantly improve the weathering resistance and provide superior protection against gloss reduction, cracking, colour change, blistering and delamination. The light stabilizers may be added in two coat applications to both the base and the clear coat. In wood coatings, combinations of TINUVIN 123 with the UV absorbers TINUVIN 384 or TINUVIN 1130 have been found highly effective in air drying alkyd based formulations. The light stabilizer blends can be added to film forming finishes as well as decorative penetrating stains. The amount of TINUVIN 123 required for optimum performance should be determined in trials covering a concentration range. Liquid HALS stabilizer based on an aminoether functionality. Its low basicity prevents possible interactions with acidic paint ingredients such as catalysts. Its efficiency provides significant improvement in coatings performance by minimizing paint defects such as cracking and gloss reduction for clear coats as well as chalking for pigmented paints. Miscible to more than 50% with most commonly used paint solvents. Water solubility is less than 0.01%. Recommended for automotive and industrial coatings, decorative paints and wood stains or varnishes. Developed especially for high solids, acid catalyzed automotive and industrial coatings, i.e. two coat metallic thermosetting acrylate systems or one coat opaque thermosetting acrylate and polyester coatings. Its high efficiency has been demonstrated in a variety of other binders and applications such as alkyd/acrylic air drying automotive refinish paints, alkyd oxidative drying paints and varnishes, two pack non-isocyanate coating technologies. Easy emulsification into water-borne systems. Can be significantly improved when used in combination with a UV absorber. Recommended usage level: 0.5-2.0% based on weight percent binder solids (+ 1.0-3.0% UV absorber) for automotive and industrial coatings, 0.5-2% (+ 1-3% UV absorber) for decorative wood coatings.
