UV-400

UV 400（DXSORB 400） is a liquid hydroxyphenyl-triazine (HPT) UV absorber with very high thermal stability and shows high thermal stability and performance for coatings exposed to high bake cycles and/or extreme environmental conditions. 

Chemical name:2-[4-[2-hydroxy-3-tridecyloxypropyl]oxy]-2-hydroxyphenyl]-4,6-bis(2,4-dimethylphenyl)-1, 3,5-triazine and 2-[4-[2-hydroxy-3-dodecyloxyprop]oxy]-2-hydroxyphenyl]-4,6-bis(2,4-dimethyl Phenyl)-1,3,5-triazine mixture

CAS：153519-44-9

UV 400 is developed as an interaction-free UV absorber for use in amine and/or metal catalyzed coating systems,to retard gloss reduction, delamination, cracking and blistering.

It is recommended for both solvent and waterborne automotive OEM and refinish coating systems, UV cured coatings, industrial coatings where long life performance is essential. The protective of UV-400 can be enhanced when used in combination with a hindered amine light stabilizer such as LS-123 or LS-292.
