LOCTITE® 641
Features and Benefits
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. 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, i.e. retention of bearings on shafts and in housings.
