  • Applications

    2-(4,6-Bis(2,4-dimethylphenyl)-1,3,5-triazin-2-yl)-5-(octyloxy)phenol (CAS 2725-22-6) is primarily utilized as a UV absorber and radical stabilizer in polymer and coating formulations. It is employed to improve photostability and color retention in coatings, paints, and inks; to enhance the long-term lightfastness of non-polar polymers such as polyolefins and other plastics; to act as a stabilizer in adhesives and sealants exposed to outdoor or industrial lighting; and to serve in protective encapsulation or optical materials used in electronics and electrical applications. It may be considered as an additive or intermediate in industrial manufacturing to mitigate UV-induced degradation, subject to formulation limits and local regulations.
