Tinuvin 405 2-[4-[(2-Hydroxy-3-(2’-ethyl)hexyl)oxy]-2-hydroxyphenyl]-4,6-bis(2,4-dimethylphenyl)-1,3,5-triazine 137658-79-8 Ciba Light stabilizer / UV-absorber >> Triazine Acrylic/Acrylate Resins Amino Resins Polyester Coatings >> Powder Coatings Automotive OEM >> Top coats >> Clearcoat Automotive refinishing >> Clearcoat General Industrial /Maintenance Powder coating >> Automotive TINUVIN 405 is a hydroxyphenyl triazine (HPT) UV absorber designed for high performance coatings. The low volatility, high thermal stability and extended UV absorption of TINUVIN 405 provides superior protection to coatings and light sensitive substances which are subjected to extreme processing conditions and light exposure. TINUVIN 405 has been developed as an interaction-free UV absorber to be used in amine and/or metal-catalyzed coating systems or in coatings applied on base-coats or substrates containing such catalysts. TINUVIN 405 is an HPT UV absorber recommended for use in coatings based on catalyzed acrylic or polyester resins. Its low melting temperature makes it an ideal product for glycidyl methylacrylate (GMA) type powder coatings. Typical application areas include: Automotive clear coats Automotive powder clear coats Powder coatings for plastics and wood High performance industrial coatings Further, the strong blue-shifted absorption properties of TINUVIN 405 makes it an attractive selection for the stabilization of high performance UV-cured systems. In such systems, photoinitiators absorbing at or above 400 nm lead to excellent through cure. TINUVIN 405 may be used in combination with other UV absorbers e.g. hydroxyphenylbenzotriazole types such as TINUVIN 1130, TINUVIN 384 or TINUVIN 928, to broaden the UV protection range for materials that are sensitive to visible light such as wood. It is recommended to use TINUVIN 405 in combination with a light stabilizer of the sterically hindered amine class (HALS) such as TINUVIN 144, TINUVIN 152, TINUVIN 292 or TINUVIN 123. These combinations provide synergistic protection effects against gloss reduction, cracking, blistering, delamination and color change. The light stabilizers may be added in clear coats, base coats or solid shades. Hydroxyphenyl triazine (HPT). Used as an interaction-free UV absorber for high performance coatings, amine and/or metal-catalyzed coating systems, coatings applied on base-coats or substrates containing such catalysts, coatings based on catalyzed acrylic or polyester resins and glycidyl methylacrylate (GMA) type powder coatings. Offers low volatility, high thermal stability, extended UV absorption, superior protection against extreme processing conditions and light exposure, low melting temperature. Can be used in combination with other UV absorbers such as hydroxyphenylbenzotriazole types to broaden UV protection range or with a light stabilizer of the sterically hindered amine class (HALS) to provide synergistic protection effects against gloss reduction, cracking, blistering, delamination and color change. <br> Applications: automotive clear coats, automotive powder clear coats, powder coatings for plastics and wood and high performance industrial coatings.
