Polyurethane modified epoxy acrylate resins containing ε-caprolactone unit

Epoxy acrylate resins modified by polyurethane with excellent mechanical properties play a crucial role in UV-curable coatings, but the high viscosity limits their further applications in 3D printing, electronic packaging material. In this work, a series of polyurethane modified epoxy acrylate resins containing various ε-caprolactone unit content were successfully synthesized to reduce the viscosity of polyurethane modified epoxy acrylate...
