Used primarily as a reactive diluent and crosslinking agent in UV-curable coatings, inks, and adhesives. Its cyclic amide structure contributes to improved adhesion, hardness, and chemical resistance in cured films. Commonly found in electronic coatings, optical fiber coatings, and printing inks where fast curing and durability are required. Also utilized in dental materials and 3D printing resins due to its balanced reactivity and low volatility.
