Abstract

The aim of this study is to evaluate the adhesive properties of UV-curing liquid (ink) on a non-porous surface. We examined how the adhesive strength was affected by the ink characteristics, as different type mono-functional monomers were used in the ink composition. The flexibility of the cured film structure seems to be crucial for improving adhesive strength, because a flexible structure can relax the internal strain that exist between the substrate and the cured film surface. It seem that when we use methacrylate type mono-functional monomers (CHMA, HEMA) in the ink composition, the two monomers play an important role in the ink system in order to reduce the crosslinking density of the cured film. Also, we understood that acrylate type mono-functional monomers (CHA, HBA) were effective to increase adhesive strength because of their low surface tension and less shrinkage, although the two inks containing each monomers formed relatively higher crosslinking density of cured films than the methacrylate type ones.
