Abstract: In recent years, with the serious surplus of manufacturing capacity, our government has paid more and more attention to environmental protection. In this case, the traditional oil paint system has been greatly impacted which leads to the rapid development of UV curing technology. Bio-based material is a kind of renewable resource. In the future, the development and application of bio-based materials become an inevitable trend with less and less non-renewable resources. The biomaterials were introduces into the UV curing prepolymer system here. The basic physicochemical properties of bio-prepolymer cured films were compared to abiotic based ones under the similar structural conditions. At last, the experimental results were summarized.

Key words: UV curing, bio-based, coating
