Abstract: Polyurethane-acrylate resin has been widely applied in industry for its execllent performance. This paper has described the development course of Uv-cured coatings since 1960 s, as well as the synthesis of Uv-cured polyurethane acrylate oligomer and recent development progress in the self-cleaning properties. The research progress of three novel Uv-curable coatings: waterborne PUA, powder PUA and modified PUA were reviewed. The deficiency and solution of novel Uv-curable PUA coatings were proposed, and the application and development trend of uv-curable coatings were prospected.
