Document Type and Number:
Japanese Patent JP2017149791
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a sealing material for preventing gas leakage capable of improving workability and effectively preventing gas leakage under various environments.SOLUTION: There is provided a sealing material for preventing gas leakage 12 which prevents gas leakage with a cured product obtained by reacting a main agent and a curing agent. The main agent contains a bifunctional epoxy resin having a bisphenol A type skeleton and an epoxy group at both terminal sides of an aliphatic skeleton composed of a long chain hydrocarbon chain and a bifunctional naphthalene-type epoxy resin. The curing agent contains a polythiol-based curing agent and a curing accelerator.SELECTED DRAWING: Figure 1
