A high-sensitivity Level 3 penetrant, ZL-67 fluorescent water removeable penetrant is designed to find smaller, finer indications in safety-critical components common to aerospace and engineering applications. ZL-67 penetrant is often used to find flaws in investment castings, jet engine components, and highly machined surfaces. ZL-67 is specially formulated for strong capillary action which allows it to penetrate defects quickly and bleed out into developer faster and more completely than other penetrants for stronger, higher contrast indications that are easier for inspectors to identify, even when the defects are very fine. 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. KEY FEATURES Level 3 high sensitivity Water washable Bright, high-contrast indications High flash point Wide range of application methods Controlled washability Low odor Very low toxicityAlloy compatibility High water tolerance High thermal resistance High UV stability Optimized capillary action Low volatility QPL SAE AMS 2644 Qualified Product List Approved for use by Pratt & Whitney Applications 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 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 More reliable, consistent inspections Maintain penetrant system performance over longer periods of time thanks to low volatility and high water tolerance Compliance AECL AMS 2644 ASME BPVC ASTM E1417 ASTM E165 Boeing BAC 5423 PSD 6-46 or 8-4 Boeing PS-21202 GE P3TF2 Honeywell EMS 52309 ISO 3452-2 MIL-STD-2132 MIL-STD-271 NAVSEA T9074-AS-GIB-010/271 Pratt & Whitney PMC 4360 QPL SAE AMS 2644 APPLICATIONS Defect location: open to surface Ideal for: Precision castings Precision forgings Machined components Investment castings Jet engine components Highly machined surfaces Aerospace alloys Aluminum Steel Nickel Titanium Defect examples: Cracks Seams Porosity
