The UV curing kinetics of coating containing siloxane modified polyurethane-acrylate were studied using photo-DSC (DPC). The effects of some factors such as incident light intensity, initiator concentration, reaction temperature on the curing kinetics have been analysized from DPC data. The curing kinetic parameters (kp and kt) for prepolymers have also been determinedv by combining steady state and non-steady state kinetics.

In ouder to prepare the waterborne UV-curable polyurethane acrylate coatings, the anionic polyurethane acrylate emulsifier and bisphenol-S eopxy acrylate were synthesized. The curing process, kinetics and properties of waterborone UV-curable epoxy acrylate/polyurethanes acrylate coating were investigated by FTIR, DSC and DMA. The results show that the static initial curing temperature Ti is 52.36 oC, peak temperature Tp is 71.58 oC, the finished temperature Tf is 89.15 oC. The curing reaction can be described by two-parameter autocatalytic Šesták-Berggren (S-B) model.This coating has a better UV-curing property. The dynamic mechanical analysis showed that the glass transition temperature Tg of coating film is 52.70 oC.
