The research progress of photo-curing epoxy acrylic resin and modified cardanol resin and its application in coatings were mainly introduced.The various methods are used to modify epoxy acrylate resin to reduce toxicity and increase its performance.A biomass material,cardanol resin,was discussed.It was found to have not only photo-curable properties,but also reduced material toxicity.It can also be combined with various solvents to form high-performance materials.
