Zyglo® ZL-60D Water Washable Fluorescent Penetrant
Level 2 Water Washable Fluorescent Penetrant
Developed for testing rough machined surfaces, ZL-60D medium sensitivity (Level 2) fluorescent water washable penetrant will readily wash off textured surfaces to find indications in castings, forgings, extrusions, and rough machined surfaces. Indications appear for cracks, seams, laps, cold shuts, laminations and porosity. ZL-60D is safe to use on most engineering and aerospace alloys, such as aluminum, steel, nickel and titanium. The high flash point of ZL-60D allows its use in open tanks. Developers recommended are ZP-4B dry powder, SKD-S2 or ZP-9F solvent-based or ZP-5B water based.
ZL-60D is listed on the QPL SAE AMS 2644 Qualified Product List and is approved for use by Pratt & Whitney.
