Abstract: In this paper, the engineering applicability of epoxy resin/solidification agent is studied. The temperature change law of the solidification process of sealing material is explored and the temperature rise limit value is determined. The concrete HIC sealing process with the epoxy material was verified by engineering scale equipment. The results show that the operational performance, temperature rise amplitude and impact resistance of the epoxy resin/solidification agent meet the application conditions of HIC sealing engineering.

Key words: epoxy resin, High Integrity Container (HIC), sealing material
