Widely used as a high-performance light stabilizer in polymer systems, this compound effectively protects materials against UV degradation. It is commonly incorporated into coatings, plastics, and adhesives to prevent yellowing, gloss loss, and mechanical deterioration caused by prolonged sunlight exposure. Its excellent compatibility with both polar and non-polar matrices makes it suitable for use in polyurethanes, acrylics, and polyester-based formulations. Due to its strong absorption in the UV-A and UV-B range and high thermal stability, it is especially effective in outdoor applications such as automotive finishes, industrial coatings, and agricultural films. The presence of the hydroxyalkoxy structure enhances its ability to function synergistically with other stabilizers, improving overall durability and extending service life of the material.
