Photosensitive organofluorine and organosilicon play a key role in improving the properties of UV‐curing coating materials. In this study, by using 2,2,3,4,4,4‐hexafluorobutyl methacrylate (HFMA) and a synthesized side methacryloxy group polysiloxane (MAPS) as modifying materials and bisphenol‐A epoxy methacrylate (BEMA) as matrix, respectively, a innovative UV‐curing system, BEMA/HFMA/MAPS composite system was developed. Through UV‐cure process, a series of BEMA/HFMA, BEMA/MAPS, and BEMA/HFMA/MAPS cured composite films with different proportions were successfully obtained. It was found that HFMA monomer was helpful for the reduction of the surface energy of the UV‐cured composite films and the enhancement of their water resistance property. Without HFMA in BEMA matrix, MAPS could facilitate the improvement of the properties of BEMA/MAPS cured films, and the presence of MAPS in BEMA/HFMA/MAPS system could significantly decrease the surface energy of the cured films to 22.1 mJ/m 2 and improve their thermal stabilities and water resistance properties by measurements, contact angle, TGA, DSC, and water resistance. To the SEM observation, HFMA and MAPS were well distributed in the cured films in favor of their excellent performances. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
