Safety & Health

Precautions

Silicone greases may be cleaned with non-polar solvents such as toluene, hexane, and mineral spirits. Whenever using solvents be certain to observe all proper, safety precautions. Not for application on surfaces that are to be painted consult and obey all applicable local, state, and federal regulations for disposal of solvent and silicone waste.

Packaging & Availability

Packaging Type
Availability

Versilube G351 is available in 5.3 ounce tubes, 1 gallon pails, 5 gallon pails, and 55 gallon drums.

Storage & Handling

Storage

Versilube G351 has a shelf-life of sixty (60) months from the date of manufacture when stored in the original, unopened container at, or below, 100ºF. Upon prolonged storage, it is normal for a small amount of fluid bleed to appear on the surface of the grease. This condition is not detrimental to the performance and the fluid is simply mixed back into the suspension.
