  • Applications

    ADKStabNA21E (CAS 151841-65-5) is a hindered amine light stabilizer (HALS) used as a polymer stabilizer to mitigate UV- and thermo-oxidative degradation of plastics. In practice, it is applied in polymer formulations to protect polyolefins, polycarbonates, and polyamides; in coatings and inks as an additive to improve UV stability and color retention of coatings and printed materials; in adhesives and sealants to enhance long-term light stability of bonded assemblies; in resin systems and formulated packaging materials such as films and laminates to extend outdoor durability; and in outdoor and automotive applications where exterior materials require sustained light stability. Subject to local regulations and formulation limits.
