UV-curable resins have been used as protection coating layers in display industry, such as glass slimming of liquid crystal display (LCD) and manufacturing of anti-glare glass. They could be manufactured by etching of the glass surface. During the glass etching, some part of the glass substrate must be protected by UV-cured resins to prevent direct contact with the etchant. In these glass etching processes, hydrofluoric acid (HF) is often used as the etchant, and thus UV-cured resins with high acid-resistance are required. In this study, we prepared various UV-curable resins consisting of a urethane acrylate oligomer, an acrylate monomer, an acrylate cross-linker, and a photoinitiator. The resins with various compositions were cured by UV irradiation, and then their resistance to chemicals such as acid, alkali and organic solvents was investigated. Adhesion properties of the resins were also evaluated.
