Tinuvin 928 2-(2H-Benzotriazol-2-yl)-6-(1-methyl-1-phenylethyl)-4-(1,1,3,3-tetramethylbutyl)phenol 73936-91-1 Ciba Light stabilizer / UV-absorber >> Benzotriazole Coatings >> Powder Coatings Automotive OEM Automotive refinishing Coil Coating *HQHUDO TINUVIN 928 is a new UV absorber of the hydroxyphenyl benzotriazole class developed specially for high performance coating applications. The characteristic broad band absorption of TINUVIN 928 provides efficient protection to coatings and light sensitive substrates. The product has excellent solubility and high thermal and environmental permanence, which makes it particularly suitable for coatings exposed to high temperature curing processes, such as powder and coil coatings, or high environmental stress. $SSOLFDWLRQV TINUVIN 928 is recommended for applications such as: · automotive coatings · powder and coil coatings TINUVIN 928 may be used in combination with a light stabilizer of the sterically hindered amine class (HALS) such as recommended below. Combinations provide best protection against gloss reduction, cracking, blistering, delamination and color change. The light stabilizers may be added in clear coats, base coats or solid shades. However, according to our experience the optimum protection is achieved by adding the light stabilizers to the topcoat. The amount of TINUVIN 928 required for optimum performance should be determined in trials covering a concentration range. UV absorber of the hydroxyphenylbenzotriazole class developed specifically for high performance coating applications. Provides efficient protection to coatings and light sensitive substrates. Excellent solubility and high thermal and environmental permanence, which makes it particularly suitable for coatings exposed to high temperature curing processes, such as powder and coil coatings, or high environmental stress. Recommended for automotive coatings, coil coatings, powder coatings. May be used in combination with a light stabilizer of the sterically hindered amine class (HALS). 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. Optimum protection is achieved by adding the light stabilizer to the topcoat. Recommended usage level: 1-3% based on weight percent binder solids (+0.5-2% HALS) for powder and liquid coatings.
