There are various thin coating technologies, among which the UV coating technology is attracting attention in next-generation industries. In order to utilize the UV coating system stably, it is necessary to analyze and address the problems of surface oxygen inhibition and UV penetration, which lead to irregular curing characteristics. For this, three different UV-curing resins were selected. The effects of the structural difference of the material and change in the initiator content along the thickness direction during UV curing were evaluated by the sliding cutting technique (which involves cutting the coated surface at a superfine angle). Thus, it was confirmed that the effect of surface oxygen inhibition during UV curing is very large on the surface. Here, surface curing could be induced by increasing the functional group concentration and introducing a hybrid curing system. With increasing initiator content, the formation of a material with a high curing density on the surface and an irregular hardening structure in the deep part was confirmed. Therefore, the sliding cutting technique is a very effective approach to control the thickness profile of a UV coating system.
