In the present research, cardanol based di-acrylic UV oligomer was synthesized by thiol-ene coupling followed by ring opening reaction with glycidyl methacrylate. The intermediate as well as final diacrylate materials were analyzed by chemical as well as spectroscopic analysis. Further, ultraviolet (UV) radiation curable formulations were prepared by replacing commercial epoxy acrylate with synthesized UV oligomer in 10-50 wt% and applied on wood panels. The coated films were then evaluated for their optical, mechanical, chemical and thermal properties. Studies showed that up to 30 wt% amount of UV oligomer the coatings exhibited at par mechanical and chemical properties. The stain resistance of all the coatings was observed to be excellent.
