Dual-curing behavior and scratch characteristics of hydroxyl functionalized urethane methacrylate oligomer for automotive clearcoats

► Synthesis of dual-curable, hydroxyl methacrylate functionalized urethane oligomers (HFUMOs). ► Incorporation of HFUMOs in clearcoats to scrutinize mechanical and scratch characteristics. ► Enhanced clearcoat properties and effective curing control by UV-thermal dual curing sequence.
