XP 2C4

Performance Lubricants

Grease for Anti-Fretting Applications

Product Information
Krytox™ oils and greases are based on perfluoropolyether(PFPE) oils. These synthetic fluorinated lubricants
are used in extreme conditions such as continuous
high temperatures up to 300 °C (572 °F) and higher
temperatures for shorter periods, depending on productgrade limits. They are nonflammable and safe for use
in oxygen service. They are chemically inert and usedsafely around hazardous chemicals. They do not damage
plastics or elastomers nor cause corrosion to metals.
They are commonly used as lubricants in aerospace,automotive, industrial, and semiconductor applications, aswell as solving many other routine lubrication problems.
Krytox™ XP 2C4 grease contains an oil soluble additivethat is effective at preventing corrosion and reducing
wear. It also contains a micro-powder boron nitride
extreme pressure additive. Typical applications include
those in potentially corrosive atmospheres, wherevibrational or shock loading may be significant and anelement will spend more time experiencing mixed film
or boundary lubrication versus the desired full film orhydrodynamic lubrication.

Krytox™ oils and greases are silicone-free. They do notcontain any VOC materials or chlorine and are nothazardous to the atmosphere or ozone layer. They are
biologically and environmentally inert.

Typical Applications

Dropping Point

N/AKrytox™ lubricants are generally used in applications of a
critical nature due to extreme temperatures or aggressive
environments that conventional lubricants are not able towithstand and are now often considered an integral partof the design. When failure of components is not an option
because of durability, warranty, safety, loss of productivity,or downtime, Krytox™ is the lubricant of choice in a wide
range of industries and applications.

Packing the Bearing

Storage and Shelf Life

New unlubricated bearings often have rust preventive
oils in them to prevent damage while they are in storage
before use. New bearings should be inspected for damage
and cleanliness before use. The greases or preservativeoils need to be removed when using Krytox™ as a lubricant.
Failure to do so could result in reduced bearing life.
Bearing life tests on uncleaned bearings have shown
reduced life in high temperature, high speed tests wherethe bearing was filled with a minimum amount of grease.

The XP series of Krytox™ lubricants can develop an odor
and a slight amber/pinkish color over time. The XP series
has a three-year shelf life and a recommended maximum
operating temperature of 182 °C (360 °F). Testing has
shown that these products retain their anti-rust andanti-wear properties and perform well past the end of therecommended three-year shelf life. Keep product sealed
and store in a cool, dry place.

The preservatives coat the metal surface to prevent
rusting so they can also prevent the grease from adhering,causing them to be thrown off by the action of thebearing. They also will oxidize and harden and can create
debris that will contaminate the grease.
