Widely used as a high-performance ultraviolet (UV) absorber in polymer systems, this compound effectively stabilizes materials against photo-degradation caused by long-term sunlight exposure. It is particularly effective in polycarbonates, polyesters, and acrylics, where it helps maintain clarity, strength, and color stability. Due to its strong absorption in the UVA and UVB range and excellent thermal stability, it is commonly incorporated into coatings, films, and outdoor applications such as automotive parts and construction materials. Its molecular structure allows for good compatibility with aromatic polymers and reduces the risk of migration or volatility during service. Additionally, it finds use in specialty applications like optical devices and UV-protective films where long-term durability is critical.
