Hi-temp epoxy

Pyro-Putty 657, a high-temperature, protective epoxy system is used by coal-burning power plants to repair corrosion defects in stainless steel containment panels which are installed to reduce the loss of exhaust gases thru boiler system ash pit and hoppers. The epoxy is a trowelable, one-to-one two-part, metal-filled system which is stable to 400 F.
