Used primarily as a high-performance light stabilizer in polymers, this chemical protects materials from degradation caused by UV radiation and oxidative stress. It is especially effective in polyolefins, polyurethanes, and engineering plastics exposed to outdoor environments. The compound prevents yellowing, cracking, and loss of mechanical strength in plastics used for automotive parts, agricultural films, coatings, and exterior building components. Due to its low volatility and high thermal stability, it remains active during long-term exposure and processing at elevated temperatures. Its multi-site structure enhances efficiency by providing synergistic stabilization, making it suitable for demanding applications where durability is critical.
