Synthesis and properties of UV-curable tung oil based resins via modification of Diels-Alder reaction, nonisocyanate polyurethane and acrylates

► UV-curable tung oil resins are prepared via Diels-Alder reaction, modification of nonisocyanate polyurethane (NIPU) and acrylates. ► NIPU improves tung oil based resins as well as solves problems of traditional PU technology. ► Acrylated modification keeps advantage of fast cure along with industrial and commercial acceptance.
