Description

The aim of this research is to evaluate the adhesive property of UV-curing ink on a non-porous surface. Generally speaking, it seems that surface tension and shrinkage of functional monomers are very important factors for a good adhesive property of the cured film. We found that the flexibility of the cured film is influenced by the chemical structure of both di- and tri-functional monomers. The flexibility seems to be crucial in improving bonding strength. It is important for the tri-functional monomer to have long-chain spacer groups in order to get a good adhesive property. Meanwhile, di-functional monomers having long-chain spacers, tend to form a dense network structure among the ink components. In this case, the cured films show a poor adhesive property.
