Used primarily as an intermediate in the synthesis of hindered amine light stabilizers (HALS), this compound plays a critical role in enhancing the weatherability and longevity of polymers exposed to UV radiation. It is incorporated into plastics, coatings, adhesives, and textiles to prevent photodegradation, thereby maintaining mechanical strength, color, and appearance over time. Its derivatives are especially effective in polyolefins, polyurethanes, and automotive coatings where long-term UV stability is essential. Additionally, it helps reduce the rate of surface cracking, chalking, and yellowing in outdoor applications.
