Magnaflux Fluorescent Post Emulsifiable Penetrants

ZYGLO Penetrant Materials

Overview

Fluorescent Post Emulsifiable penetrant materials are used with the Liquid Penetrant inspection method to locate surface flaws in non-porous parts. Available in liquid form (ZL-27A and ZL-37 Aerosols have been discontinued). Choose from three sensitivity levels to satisfy military, industry or company specifications. ZYGLO formulas offer improved sensitivity, brightness, and resistance to over washing.

ZL-2C, Level 2, Methods B/C/D

A medium sensitivity penetrant (Level 2), ZL-2C fluorescent post-emulsifiable penetrant is designed to be removed from the part surface by emulsifiers or solvent. With a UV-A light source, indications will appear as a bright green-yellow fluorescence. ZL-2C has a high flash point, and is designed to be used in open dip tanks. ZL-2C is listed on the QPL SAE AMS 2644 Qualified Product List and is approved for use by Pratt & Whitney.

Features

  • Level 2 medium sensitivity
  • Methods B/C/D - Post Emulsifiable, lipophilic and hydrophilic & Solvent Removable
  • Bright indications
  • Minimal background fluorescence
  • High flash point
  • QPL SAE AMS 2644 Qualified Product List
  • Approved for use by Pratt & Whitney

ZL-27A, Level 3, Methods B/C/D

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. 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​

Features

  • Level 3 high sensitivity
  • Methods B/C/D - Post emulsifiable lipophilic and hydrophilic & Solvent removable
  • Bright indications
  • Resists over-washing or over-removal
  • High flash point
  • Wide range of application methods
  • Low odor
  • Very low toxicity
  • Alloy compatibility
  • High thermal resistance
  • High UV stability
  • QPL SAE AMS 2644 Qualified Product List
  • Approved for use by Pratt & Whitney

ZL-37, Level 4, Methods B/C/D

Essential for critical component applications, ultra-high sensitivity ZL-37 post-emulsifiable penetrant is designed for detecting fine, tight discontinuities in safety-critical components, such as titanium turbine components, and in high-stress parts, such as investment castings. This Type 1 penetrant is non-water-soluble so there is minimal risk of washing ZL-37 penetrant from a fine or shallow defect which makes this penetrant inspection the most reliable, dependable form of PT testing. ZL-37 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. ZL-37 is listed on the QPL SAE AMS 2644 Qualified Product List and is approved for use by Pratt & Whitney.

Benefits

Improve Indication Detection in the Most Critical Applications

  • Creates the clearest, brightest indications for even the finest flaws due to very strong UV and thermal stability
  • Highest fluorescent brightness of any Level 4 penetrant for high-contrast indications that are easy for inspectors to see – even when the indications are very small
  • 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-37 cannot be removed with water (unless combined with an emulsifier)
  • Post Emulsifiable 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

Features

  • Level 4 ultra-high sensitivity
  • Methods B/C/D - Post emulsifiable lipophilic and hydrophilic & Solvent removable
  • Bright, high-contrast indications
  • Resists over-washing or over-removal
  • High flash point
  • Wide range of application methods
  • Low odor
  • Very low toxicity
  • Alloy compatibility
  • Very high thermal resistance
  • Very high UV stability
  • High dye content
  • QPL SAE AMS 2644 Qualified Product List
  • Approved for use by Pratt & Whitney
