In this study, to develop the adhesives with improved waterproof properties for display application, UV-curable urethane acrylate oligomers containing a fluorine moiety were synthesized from hydrogenated polybutadiene diol (HLBH-P2000), perfluoropolyether diol (HTPFPE), isophorone diisocyanate (IPDI) and 2-hydroxyethyl acrylate (HEA). The properties which were related waterproof performance such as contact angle, surface energy and water vapor transmission ratio (WVTR) of synthesized fluorine induced urethane acrylate oligomers were measured. As the HTPFPE content increased, the contact angle also increased from 97.9 degree to 104.4 degree. The surface energy and WVTR decreased as the HTPFPE content increased. The adhesion strength also decreased according to the HTPFPE content increased, and the adhesion strength reduction had greatly increased as the HTPFPE content increased. The findings of this study will be beneficial for developing waterproofing adhesives in the field of display which has recently been a waterproof issue.
