Description

Post-emulsifiable ZL-27A is a Level 3, high-sensitivity Type 1 penetrant designed for inspections which require maximum process control and reliability, such as safety-critical aerospace testing.

Since ZL-27A is not water soluble, there is minimal risk of this penetrant being removed from a fine or shallow defect through over-washing to provide the highest reliability of any penetrant inspection method.

ZL-27A has a high flash point and provides long tank life when used in open dip tanks, but this penetrant can also be applied in a variety of other ways, including electrostatic spray.

To remove surface ZL-27A penetrant before developer application, use ZE-4E Method B lipophilic emulsifier or ZR-10E Method D hydrophilic emulsifier can be used.

ZL-27A is listed on the QPL SAE AMS 2644 Qualified Product List and is approved for use by Pratt & Whitney.

Benefits

Improve indication detection

  • Clear, bright indications are easier to detect due to high UV and thermal stability – even for small flaws and discontinuities
  • Indications stand out more since background fluorescence is minimized; emulsifiers only remove surface penetrant without the risk of over-washing

Maximize penetrant inspection process control

  • Prevents over-washing since ZL-27A cannot be removed with water (unless combined with an emulsifier)
  • PE penetrant system is less susceptible to human error since only surface penetrant is removed in the final rinse stage

Wide range of inspections

  • Inspect a wide range of high-value components without fear of corrosion or specification non-conformance
  • Meets all major industry and NDT specification requirements, including Aerospace Prime and OEM specs, AMS 2644 and ISO 3452

Maximize operator comfort and safety

  • Promotes better inspection quality by providing the operator with a more comfortable work environment
  • Reduces discomfort from strong odors
  • Exceeds all EHS requirements
