Curing behaviour of uv-led curable urethane acrylate coating

Recently, UV radiation coating has been tremendously utilized in coating as it demonstrated fast curing and solvent free formulation. In this study, UV-LED technology was employed as a new alternative to conventional UV coating with safer environment and better perfomance. The UV curable coating was...
