Tinuvin 400-2 Mixture of 2-[4-[(2-Hydroxy-3-dodecyloxypropyl)oxy]-2-hydroxyphenyl]-4,6-bis(2,4-dimethylphenyl)-1,3,5-triazine and 2-[4-[(2-Hydroxy-3-tridecyloxypropyl)oxy]-2-hydroxyphenyl]-4,6-bis(2,4-dimethylphenyl)-1,3,5-triazine 153519-44-9 Ciba Light stabilizer / UV-absorber >> Triazine Amino Resins Automotive OEM Automotive refinishing General Industrial /Maintenance 1-Methoxy-2-propylacetate Miscible in organic solvents Immiscible in water TINUVIN 400-2 is a hydroxyphenyltriazine class liquid UV absorber for coatings. Its very high thermal stability and permanence makes it suitable for coatings exposed to high bake cycles and/or extreme environmental conditions. TINUVIN 400-2 has been developed as an interaction-free UV absorber to be used in amine and/or metal catalysed coating systems or in coatings applied on base-coats or substrates containing such catalysts. The product has been designed to fulfill the high performance and durability needs of automotive and industrial finishes. TINUVIN 400-2 is recommended for automotive OEM and refinish coating systems based on amine and/or metal catalysed systems. The protective effects of TINUVIN 400-2 can be enhanced when used in combinations with a HALS light stabiliser such as TINUVIN 123 or TINUVIN 292. These combinations improve the durability of clear coats by retarding gloss reduction, delamination, cracking and blistering. Use level: 1-3% based on weight percent binder solids.
