Loctite 641 Retaining Compound

Loctite 641 is designed for the bonding of cylindrical fitting parts, particularly where disassembly is required for servicing operations. The product cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage due to shock and vibration. Ideal for parts that need subsequent dismantling, that is retention of bearings on shafts and in housings.
