ZL-27A

Level 3 Post Emulsifiable Fluorescent Penetrant

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.

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 minimised; 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
    • erospace Prime and OEM specs, AMS 2644 and ISO 3452.
  • Maximise 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
