Paper Title:
UV-Curable Coating of Epoxy-Acrylate/Polyurethane-Acrylate Nanocomposites Modified with V-POSS
  Abstract

UV-curable bi-component coating of epoxy-acrylate/polyurethane-acrylate modified with polyhedral oligomeric silsesquioxane containing vinyl group (V-POSS), and UV-cured process and kinetics were investigated by FTIR, DSC, and DMA. The results show that this coating has a good UV-curable property, and the two components have very good compatibility and can co-cure in free radical polymerization. The curing reaction can be described by a two-parameter autocatalytic Šesták-Berggren (S-B) model. The modified UV-curable coating has good adhesive strength for steel and hardness. The mechanical loss peak temperature Tp is highest when the content of V-POSS is 60%, which is increased by 5.2 oC than the pure system.
