This difunctional acrylate compound serves as a reactive UV absorber in UV-curable polymer systems. It incorporates 2-cyano-3,3-diphenylacrylate chromophores that absorb ultraviolet light in the 300–400 nm range, protecting materials from photodegradation, discoloration, and cracking caused by sunlight exposure. The polymerizable acrylate groups allow it to covalently bond into the polymer network during free-radical UV curing of acrylate-based formulations, ensuring non-migratory UV stabilization. Key applications include UV-curable inks, coatings, adhesives, plastics, resins, fiberglass, lubricants, dental composites, and 3D printing resins, where it enhances durability, thermal stability, and resistance to yellowing in thin films and clear products exposed to UV light.
