Retaining Compound - medium strength. If disassembly is required. Ideal for parts that need subsequent dismantling. Loctite 641 is designed for the bonding of cylindrical fitting parts, particularly where disassembly is required for servicing operations. Features and Benefits High strength formulation means the retaining compound is ideal for use on close-fitting cylindrical parts This product cures when confined in the absence of air between close-fitting metal surfaces and prevents loosening and leakage due to shock and vibrationTypical Applications Ideal for parts that need subsequent dismantling, i.e. retention of bearings on shafts and in housingsNotes Colour: Yellow Temperature range: -55 to 150C
