LOCTITE 640 - 250ml (anaerobic, high strength green retaining compound for cylindrical assemblies)
LOCTITE® 640
Product Description
LOCTITE® 640 is designed for the bonding of cylindrical fitting parts. The product cures when confined in the absenceof air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration. Typical applications include retaining keys and splines, eliminating backlash in worn assemblies, retaining bearings in place - preventing spin out, retaining rotor to shafts in fractional and subfractional horsepower motors, retaining bushings and sleeves in housings and on shafts, augmenting press fits, restoring the fit to worn assemblies or out of tolerance parts.
Properties
- Slow curing for long assembly time,
- Ideal for large diameter components,
- High-strength,
- Good temperature resistance.
