LOCTITE® 648 Retaining Compound

Features and Benefits

This low viscosity, high strength, anaerobic-curing retaining compound is designed for bonding cylindrical fitting parts. Even works on slightly oily surfaces e.g. from various oils, such as cutting fluids.
When you’re working with holding gears and sprockets on gearbox shafts, or rotors on electric motor shafts, LOCTITE® 648 is ideal for preventing loosening and leakage from shock and vibration. This green, low viscosity, high strength, anaerobic-curing retaining compound provides reliable bonds of cylindrical assemblies, even when exposed to high temperature environments. It cures on active metals (e.g. mild steel) as well as passive substrates like stainless steel and plated surfaces, and it even tolerates minor surface contaminations from oils such as cutting, lubrication, anti-corrosion and protection fluids without the use of a primer or cleaner.
