The PUA was prepared with 2,4-tolylene diisocyanate, polyethylene glycol, and hydroxyethyl acrylate. The electron beam was used to cure the coatings. The samples were characterized by FTIR and TGA to investigate the law of the absorbed dose and the properties of the products after electron beam curing. The results showed that the absorbed dose had great effects on the characterization of the cured PUA coatings, and the samples irradiated with dose of 60−80 kGy had good mechanical properties, high gel fraction and thermal stability.
