Used primarily as a UV light stabilizer in polymers, this compound protects materials from degradation caused by sunlight and environmental exposure. It is especially effective in plastics, coatings, and adhesives where long-term weatherability is required. By scavenging free radicals formed during UV exposure, it helps prevent discoloration, cracking, and loss of mechanical strength. Commonly found in automotive parts, outdoor textiles, and packaging films, it enhances product lifespan without affecting clarity or flexibility. Its compatibility with other stabilizers and low volatility make it suitable for both industrial and consumer-grade materials.
