Lubrication Points for Non-Bearing Automotive Applications

Product Information
High Performance Lubricants That Work in Demanding
Real-Life Applications
Reliable high-performance fluoropolymer lubricants fromChemours can stand up to even extreme conditions. Krytox™
oils and greases have proven scientific and technicalproperties to help solve the most critical issues in theautomotive industry. Superior product performance, lower
overall maintenance systems cost, and a lower environmental
footprint help to meet rising consumer expectations. For
automotive manufacturers, this provides the opportunity tooffer extended warranties and enjoy improved productivity
through reduced component failure.
Krytox™ oils and greases are based on perfluoropolyether(PFPE) oils. These synthetic fluorinated lubricants are
effective from –75 °C to greater than 400 °C (–103 °F to>752 °F), depending upon operating conditions and productgrade. Krytox™ oils and greases are exceptionally safe,reliable, and offer environmental benefits as well as longer
lubricant life. These oils and greases will not burn or support
combustion, even in 100% liquid or gaseous oxygen, nor will
they degrade or break down in the presence of aggressive
chemicals. In automotive applications, Krytox™ oils andgreases deliver low temperature starting performance, while
maintaining efficacy at higher temperatures. These oils andgreases can increase service life of critical components,
allowing them to run more quietly and last longer, for superior,reliable performance.

Proven Applications
Battery Vent Seals
Lead acid batteries provide a dependable, rechargeable
source of electricity for engine start-up. As the battery
recharges, hydrogen gas is produced that is then safely
released through sliding vents in the battery. These ventsare designed to allow the release of gas pressure without
the excessive evaporation of water. The ability of the vent toslide freely is crucial to ensuring the safe release of hydrogenpressure without compromising performance throughexcess water evaporation. Krytox™ lubricants have a very
low coefficient of friction, leading to excellent control andsmoother gliding of the vents. Furthermore, Krytox™ products
are compatible with the plastic in the battery housing anddo not degrade in the corrosive, acidic environment of thebattery.

Spark Plug Boots
The spark plug boot protects the spark plug from weather
and prevents the unintentional grounding of the spark energy.
The boot is made of a silicone rubber, which, over time, canbond with the silicon ceramic of the spark plug, fusing theboot and spark plug together. Once this occurs, the only
way to remove the boot is by force, which can cause enoughdamage to require replacement of the entire assembly.
Krytox™ lubricants can prevent this fusion from taking place,and they are ideal in this application because they are stablenon-reactive, and long-lasting. Krytox™ lubricants can also
withstand the high temperatures and energies of the spark
plug environment.

Cooling System Thermostat
The automobile’s cooling system allows the engine to warm
up quickly and also helps maintain its optimal operating
temperature by removing heat as necessary. The system iscontrolled by a thermostat that determines whether coolant
flows through the radiator (removing heat and allowing for
optimal temperature maintenance) or is diverted back to thepump (allowing the engine to warm up more quickly). Coolant

flow is controlled by a temperature-dependent valve (orthermostat) that either opens or closes, depending on need.
The valve that allows coolant to flow through the radiator isopened by an actuator rod that must be able to slide without
resistance. Increased friction reduces the thermostat’s
ability to regulate an engine’s temperature and can result in
longer warm-up time and higher engine temperatures, which
will decrease performance and can lead to engine damage
or failure. Proper lubrication of this rod with Krytox™ highperformance lubricant ensures long-term optimal engine
performance and gas mileage.

O-Ring Lubrication/Assembly Lube
O-rings effectively seal many interfaces in an automobile.
A lubricant is often applied to keep seals in place duringassembly and allow them to assemble without damage.
Choice of lubricant is critical: if the wrong lubricant is used fora given seal material, the seal could degrade prematurely andcause serious damage. Krytox™ lubricants are the preferredchoice because they are compatible with all seal materials.
Furthermore, Krytox™ lubricants do not contribute to sealdegradation, because they do not oxidize and have greatertemperature stability than the seals.

EGR Valve
The exhaust gas re-circulating (EGR) valve reduces NO x
formation by re-circulating some of the exhausted gas backinto the engine cylinders. This lowers the peak temperaturesinside the cylinder, thus reducing the rate of NO x formation.
If the valve does not open enough, insufficient re-circulation
takes place, and excess pollution is created. If, however, thevalve sticks open, the temperature inside the cylinder candrop too much, decreasing engine performance and fuelmileage. Krytox™ lubricants are an ideal choice, because
they withstand the high temperatures and exhaust fumes
experienced by the EGR valve.

Engine/Turbo Cooling System
Slip fittings and lubing assemblies are difficult to assemble
and remove for maintenance or replacement. Krytox™ cansolve the problem. Krytox™ products are compatible withmost metal, plastic, and rubber interfaces, and they canreduce the friction in the assemblies, ultimately decreasing
the time and effort needed to assemble parts. Furthermore,
Krytox™ lubricants are long-lasting, ensuring that the parts will
be much easier to disassemble and service throughout thelifetime of the vehicle.

Performance LubricantsWindshield Wiper Motor

Electronic Parking Brake Mechanism

Failure of the windshield wiper motor is a dangerous situationthat can be avoided by the application of a small amount of
Krytox™ on the bushings. Krytox™ has a very low coefficient offriction on startup, so a small amount leads to a significant
reduction in friction. This translates into less work for thewindshield wiper motor, giving it a much longer life.

Some vehicle manufacturers are replacing the conventional
mechanical parking brake with an electronic one, wherea simple push button assisted by a small plastic gearbox
engages the brake. Failure of this mechanism could beserious. Krytox™ can carry the gear load, won’t evaporate
or oxidize, and is compatible with all plastics. As a result of
these excellent lubricant properties, it is expected to work forthe lifetime of the car, and can reduce both safety issues andwarranty claims.

Super Charger Lubricant
Krytox™ grease is applied to a spring-loaded engineered
plastic bushing to remove any backlash from thesupercharger dual rotor drive train. The thermal and oxidative
stability properties of Krytox™ lubricants, as well as theirunique frictional characteristics, make them ideal for thistype of application, delivering very long life and incrediblysmooth, stick-slip free performance.

Exterior Side View Mirror Mechanism
The angle of the exterior side view mirror is adjusted using
small plastic gears that can easily crack or break if evenminor binding occurs. The application of Krytox™ greaseprovides long-lasting lubrication, eliminating the need forregular maintenance, and ensuring continuous, reliable
operation of the mirror for the life of the vehicle.

Minivan Side Door Motor Clutch
This is an application requiring very specific frictional
characteristics as well as performance over a long warranty
life. Resistance to lubricant washout as well as tolerance
to dirt are important lubricant characteristics. Krytox™ has
once again excelled in performance in a unique and very
challenging application, where traditional lubricants simply
can’t meet the performance demands and extended warranty
requirements.
