2,2',4-Trimethoxybenzophenone is a specialty chemical primarily used as a UV absorber and light stabilizer in the polymer and plastics industries. It effectively absorbs ultraviolet radiation to prevent photodegradation, thereby enhancing the durability and weather resistance of materials such as outdoor plastics, coatings, films, and adhesives. This compound is essential for extending the service life of products exposed to sunlight, including automotive parts, packaging, and construction materials, ensuring improved performance and reduced yellowing or brittleness over time.
