We studied about properties of the UV-curable coating liquid that contains epoxy prepolymer and monomers. In order to understand the adhesion characteristics of cured films, we investigate the physical/chemical properties of the curing liquid, which have tri-functional monomers using different chain lengths. We found out that the liquid-A including tri-functional monomers (TMPTA, EO(3)-TMPTA) have a better adhesive strength than the liquid-B just including TMPTA, since the tri-functional monomer EO(3)-TMPTA that have a long chain length of the chemical structure than that of TMPTA plays an important role to make a flexible structure of the cured film.
