UV curing polyurethane acrylate（PUA）coatings provides high reactivity，fast curing，and low volatile organic compound（VOC）emission.Curing films of PUA coatings shows excellent adhesion，flexibility，abrasion resistance，chemical resistance and weather resistance. Therefore PUA coatings are the ideal coatings for high performance，energy saving and environmental protection.This paper described the synthesis of traditional PUA from three aspects： principle，routes and methods，and compared the advantages and disadvantages of each synthetic route and synthesis method.Then illustrated the synthesis principle，advantages and disadvantages of three new PUA systems：waterborne PUA，hyperbranched PUA and bio-based PUA. And reviewed three modified PUA systems in terms of modification principles and research progress：organic fluorine modified PUA，silicone modified PUA and nanoparticle modified PUA.Finally，the development trend of PUA coatings was prospected in light of the current status.
