LOCTITE 640 IN 250 ML BOTTLE

LOCTITE 640 - BOTTLE 250 ML

LOCTITE 640 is designed for the bonding of cylindrical fitting parts.

The product cures when confined in the absence of 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.
