Tinuvin 900 2-(2H-benzotriazol-2-yl)-4,6-ELV(1-methyl-1-phenylethyl)phenol 70321-86-7 Ciba Light stabilizer / UV-absorber >> Benzotriazole Coatings >> Powder Coatings Automotive OEM Automotive refinishing Coil Coating TINUVIN 900 is a UV absorber of the hydroxyphenylbenzotriazole class developed specifically for coatings. It is particularly suitable for coating systems exposed to high temperatures and/or extreme environmental stresses. It is, therefore, especially suitable in view of the high durability demands for high performance coating applications. TINUVIN 900 is recommended for applications such as: · automotive coatings · coil coatings · powder coatings. TINUVIN 900 may be used in combination with a light stabilizer of the sterically hindered amine class (HALS) such as recommended below. These combinations give coatings superior protection against gloss reduction, cracking, blistering, delamination and color change. The light stabilizers may be added in two coat automotive finishes to the base and clear coat. However, according to our experience the optimum protection is achieved by adding the light stabilizer to the topcoat. The amount of TINUVIN 900 required for optimum performance should be determined in trials covering a concentration range.
