UV curable coating materials has been widely used various industries such as automotive, coil coating, exterior wood printing and adhesives owing to environmental advantages. In this research, we synthesized eco-friendly urethane acrylate (UA) using isosorbide and other acrylate monomers to enhance film properties and their curing kinetics. Especially we used 4,4′-Methylenebis(cyclohexyl isocyanate (H12MDI) which are non-yellowing type chemicals. And another chemical of silicone acrylate was used for heat resistance. The poly urethane acrylate(PUA) was characterized by using Gel permeation chromatography (GPC). The UV-curable coatings were prepared by PUA polymer blending with a silicone acrylate and photoinitiator under the different mole ratios. |
