MagnaFlux Zyglo ZL-67 Level 3 Water Washable Fluorescent Penetrant

ZL-67 is a high-sensitivity Level 3 fluorescent penetrant designed for detecting fine defects in critical aerospace and engineering components, such as investment castings and jet engine parts. Its strong capillary action allows it to penetrate defects quickly and produce high-contrast indications that are easier to detect, even in very fine flaws.

ZL-67 is listed on the QPL SAE AMS 2644 Qualified Product List and is approved for use by Pratt & Whitney.

Recommended developers are ZP-4D dry powder, SKD-S2 or ZP-9F solvent-based, and ZP-5B suspendible developers.

Improve indication detection

• Clear, bright, indications appear every time due to high UV and thermal stability

• Higher contrast indications form due to strong capillary action, making them easier to spot

Wide range of inspections

• Inspect a wide range of high-value components without fear of corrosion or specification non-conformance

More reliable, consistent inspections

• Maintain penetrant system performance over longer periods of time thanks to low volatility and high water tolerance
