Detailed introduction
Product Description
JOM638 High Strength Retaining Compound is a
single part, medium viscosity, high strength
anaerobic resin used for bonding rigid assemblies of all types. This material can be used effectively to
increase the strength of most mechanical assemblies.
Typical Applications
JOM638 can be used in a broad variety of applications such as:
. Locking keys and splines
. Eliminating backlash in worn assemblies
. Locking bearings in place, preventing spin out
. Bonding rotor to shaft in low horsepower motors
. Locking bushings and sleeves in housings and on shafts
. Restoring the fit to worn assemblies or out- of tolerance pans

General Information
Storage
Product should be stored in a cool and dry location at temperatures between 14°F (-10°C) to 86°F (30°C). Shelf life is 2 years from date of manufacture when stored at 72±8°F (22±4°C).
Note
Using JOM638 is easy, the product is color
coded green and once cured, it seals and vibration
proofs the assembly, giving high compressive shears.
