DESCRIPTION: Mobil Aviation Grease SHC 100 is a high performance grease which combines a
synthesized hydrocarbon base fluid with a lithium soap thickener. The thickener
system provides a high dropping point, excellent resistance to water wash and a
tenacious structural stability. The unique properties provide outstanding protection
against wear, rust, corrosion and high temperature degradation. The grease is
recommended for aviation applications which need a lubricant that can perform
normal functions yet go far beyond in terms of high and low temperature and long-
life performance. The grease has an operating temperature range of -65掳F (-54掳C)
to + 350掳F (+177掳C).
CAUTION: Aviation bearing greases should not be intermixed with each other.
Precautions should be taken to ensure that this grease is not intermixed with other
wheel bearing greases and is being used in accordance with the manufacturers
guidelines. For technical Data and MSDS sheets on Mobil Aviation Grease SHC
