Used as a stabilizer in polymer systems, particularly in polyurethanes and polyolefins, to prevent degradation caused by heat and light. It acts as a hindered amine light stabilizer (HALS), effectively scavenging free radicals that form under UV exposure, thereby extending the lifespan of plastics exposed to outdoor conditions. Commonly found in coatings, automotive materials, and agricultural films where long-term weatherability is required. Also utilized in some specialty adhesives and sealants to maintain mechanical properties and appearance over time.
