Abstract
In this paper, several UV curable polyurethane acrylates were synthesized by using isophorone diisocyanate(IPDI), polyethylene glycol(PEG) , Dipropylene Glycol Diacrylate (DPGDA), trimethylolpropane triacrylate (TMPTA), and hydroxyethyl acrylate(HEA) as the raw materials and dibutyltin dilaurate(DBTDL) as the catalyst. The structure was confirmed by the Fourier transform infrared spectroscopy (FTIR). The characterization showed the coatings have a good property.
