Silver Seal II

Silver Seal II at IGS Industries

Silver Seal II is a fibrous paste sealant used for sealing rough or irregular joints of turbines, boilers, heat exchangers, compressors, pumps, blowers, piping, ducting, process furnaces, paint ovens, or any high temperature/pressure metal to metal joint, or can be used as a gasket dressing. During joint assembly, sealant will flow into rough or irregular surfaces to provide a durable seal. Silver Seal II expands under heat and cures to a leathery like consistency, and will not crack due to thermal cycling or vibration. Joint disassembly is easy as the sealant does not excessively harden which allows for quick separation.
