Widely used as a UV absorber in polymers and coatings, this compound provides excellent protection against photodegradation caused by ultraviolet light. It is especially effective in clear coatings, polyurethanes, and acrylics, where long-term stability and resistance to yellowing are critical. Commonly found in automotive finishes, industrial coatings, and adhesives, it enhances durability and extends the service life of materials exposed to sunlight. Its ability to form stable chelates with metal ions also makes it useful in corrosion-inhibiting formulations. Additionally, it is employed in some specialty plastics and elastomers to prevent UV-induced cracking and fading.
