UV curable resins have many advantages comparing to solvent based coating materials. The coating layer of UV curable resin is highly transparent and experience relatively low volume change after curing. Most of all, UV curable resins cure very fast, which is important for good productivity. But it can be difficult to control the coating condition. Through the difference of R2R and R2P, can be seen that the coating properties change depending on the atmospheric conditions. In this paper, coating properties were analyzed according to the curing state and the differences between each condition were analyze. by applying a coating process can be controlled, we can control the coating speed and improve the product characteristics. furthermore, the new process technology may be applied.
