Used primarily as a UV stabilizer in polymers, this compound helps prevent degradation caused by sunlight and environmental exposure. It is especially effective in plastics, coatings, and adhesives where long-term color and structural stability are required. Commonly found in outdoor applications such as agricultural films, automotive parts, and construction materials, it extends the service life of products by inhibiting photo-oxidative damage. Its ester-based structure allows for good compatibility with a variety of resin systems, making it suitable for use in both rigid and flexible formulations.
