产品信息
Loctite 640 is a one-component anaerobic retaining compound for bonding cylindrical fitting parts. It cures when confined between close-fitting metal surfaces and prevents loosening and leakage from shock and vibration.
- Retains bearings in place, and bushings and sleeves in housings and on shafts
- Retains keys and splines and eliminates backlash in worn assemblies
- Augments press fits and restores the fit of worn or out-of-tolerance parts
- For slip fitted, press fitted and shrink fitted assemblies
- Activator 7471 or 7649 speeds the cure on inactive metals or large gaps
- Not recommended for pure oxygen or oxygen-rich systems, or normally for plastics
