| Abstract | The cure characteristics and tensile properties of ultraviolet (UV) curable acrylic resins were investigated as a function of cure time, and types and contents of photoinitiator and reactive monomer. The change of chemical structure during curing was investigated by Fourier transform infrared spectrometer, The photoinitiators used were benzophenone, Darocur 1173, and Irgacure 184. Irgacure 184 showed the highest curing rate among them. Based on the curing rate and tensile strength of the cured resins, the optimum content of the photoinitiator was 1 phr. Reactive monomers, hexanediol diacrylate and tripropylene glycol diacrylate, were used to modify the tensile properties of the resins. The tensile strength of the cured resin was highest when the reactive diluent content was 30 phr. As cure time and the content of reactive monomer were increased the elongation at break of the resins reduced. |
