XL0545 is a non-flammable, non-corrosive, odorless, low toxicity grease that is specifically formulated for highly critical applications where any oxidizing materials present may result in catastrophic chemical or explosive reactions.

XL0545 is formulated from saturated hydrogen-free chlorofluorocarbons which are chemically inert, non-flammable, have inherently high thermal stability, excellent lubricity, high dielectric strength, high density, and non-polar characteristics.


XL0545 halocarbon grease is inert toward practically all compounds and solutions except to chemicals that are prone to attack silica (hydrogen fluoride, etc).

XL0545 is compatible with the following common chemicals, and many others not listed below or not as widely used:

• Aluminum Chloride• Hydroiodic Acid
• Ammonium Nitrate • Muriatic Acid
• Ammonium Perchlorate • Nitrogen Oxides (all)
• Antimony Trichloride• Nitrogen Trifluoride
• Boron Trichloride • Oleum
• Boron Trifluoride• Oxygen (liquid & gases)
• Bromine• Ozone
• Bromine Trifluoride (gas)• Phosphorous Oxychloride
• Calcium Hypochlorite• Potassium Perchlorate
• Chlorinated Cyanurates• Potassium Persulfate
• Chlorine • Silane
• Chlorine Dioxide • Silicon Tetrachloride
• Chlorine Trifluoride (gas) • Sodium Chlorate
• Chlorosilanes• Sodium Hydroxide (all %)
• Chlorosulfonic Acid
• Sodium Hypochlorite
• Chromic Acid• Sulfur Hexafluoride
• Chromyl Nitrate • Sulfur Trioxide
• Ethylene Oxide• Sulfuric Acid
• Fluorine (gas)• Thionyl Chloride
• Fuming Nitric Acid• Titanium Tetrachloride
• Hydrogen Peroxide• Uranium Hexafluoride
• Hydrogen Sulfide

XL0545 is NOT recommended in areas where it might come into contact with Sodium or Potassium Metals, Amines, liquid Fluorine, or liquid Chlorine Trifluoride. They should also not be used with aluminum and magnesium (and alloys of these metals) under conditions of large shear forces such as those found in threaded connections.

XL0545 will not contribute fuel in fire-prone applications.

Chemical compatibility should be tested in the field to determine final usability of the


XL0545 is stable at operating temperatures less than 204ºC and intermittently to 260ºC. Higher temperatures will accelerate the decomposition of the rust inhibitors and lubricant base stocks.


XL0545 is compatible with the following seals, rings, and gaskets:

• Buna N• PNF
• Chlorinated polyethylene• Polyamide
• Cured Epoxies• Polycarbonates
• EDPM• Polyvinyl Alcohol
• Ethylene Propylene Rubber• Teflon®
• Fluorosilicone• Urethanes
• Neoprene • Viton, Fluorel

XL0545 is NOT compatible with:

• Buna S• Silicone Rubbers
• Natural Rubber• PVC
• Polymers or copolymers of chlorotrifluoroethylene

XL0545 is non-corrosive towards metals up to about 177ºC (with the exception of copper and some of its alloys) which will discolor over 50ºC. Prior testing should be done on all metals above these temperatures.
