SEALING MATERIAL FOR PREVENTING GAS LEAKAGE, GAS LEAKAGE PREVENTION STRUCTURE AND METHOD FOR REPAIRING GAS LEAKAGE SPOT

摘要

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;COPYRIGHT: (C)2017,JPO&INPIT
