Material for locating gas leak, method for locating gas leak, material for repairing gas leak, method for repairing gas leak, and device for repairing gas leak

A gas leak locating material used for locating a gas leaking position by application of the gas leak locating material at a position suspected to have a gas leak, wherein

• the gas leak locating material contains a curable resin composition containing a polymerizable compound and a polymerization initiator,
• the gas leak locating material satisfies a formula:
• A/B≥21.0, where A represents a viscosity (Pa·s) of the gas leak locating material at 25° C. at a shear rate of 0.1 s−1 and B represents a viscosity (Pa·s) of the gas leak locating material at 25° C. at a shear rate of 10 s−1, and
• the gas leak locating material has an elastic modulus E′ of 10 MPa or higher at 50° C. after being cured, where the elastic modulus E′ is determined by performing a temperature sweep using a rheometer in tensile mode at a frequency of 10 Hz, with a temperature elevation rate of 10° C./min, over a temperature range from 25° C. through 100° C., on a cured sample of 1 mm thickness.
