  • Preferred choice for semiconductor and electronics manufacturing

Limitations & Considerations

  • Premium price — significantly more expensive than conventional greases (10-50x cost)
  • Not suitable for extremely high load applications without consultation
  • May not be compatible with certain aluminum alloys at very high temperatures
  • Limited availability compared to standard industrial greases
  • Requires specialized application procedures to avoid contamination
  • Cannot be mixed with conventional greases without losing PFPE benefits
  • Not biodegradable — requires special disposal procedures
  • Performance on ferrous metals at extreme temperatures needs verification
  • May require surface preparation for optimal adhesion
  • Limited effectiveness as an anti-seize above 260°C

Frequently Asked Questions

Q: What applications is Klüber Barrierta L designed for?

Klüber Barrierta L is engineered for Cleanroom equipment. The product is commonly specified in industries including Cleanroom equipment, semiconductor manufacturing, vacuum pumps, oxygen equipment, valves and related industrial sectors where reliable lubrication is critical.

Q: What temperature range does it operate in?

The operating temperature range is -30°C to +260°C. Always verify the specific temperature requirements for your application against the product datasheet to ensure compatibility.

Q: Is Klüber Barrierta L food grade?

Yes, Klüber Barrierta L holds NSF H1 certification for incidental food contact, making it suitable for use in food and beverage processing equipment.

Q: Can this product be mixed with other greases?

As a general engineering practice, mixing greases with different thickener types is not recommended. Incompatible thickeners can cause the grease to soften excessively or harden, potentially leading to lubrication failure. If switching from another product, it is best practice to thoroughly purge the old lubricant before applying the new one.

Q: How should this product be stored?

Store in original sealed container at 15°C to 30°C. Keep away from strong UV light sources. Do not allow contamination with other lubricants. Store separately from conventional greases. The typical shelf life is 60 months (5 years) from date of manufacture when stored in original sealed containers under recommended conditions from the date of manufacture under recommended storage conditions.
