The Magnaflux Zyglo® ZL-15B Water Washable Fluorescent Penetrant is safe for use on aluminum, steel, nickel, titanium and other alloys. The ZL-15B classifies as a Type 1, Method A, water washable, non-water based penetrant. It has a very low penetrant sensitivity level of ½.
Recommended viewing is under an ultraviolet light with a wavelength of 365 nanometers. An example of this would be the Magnaflux® ZB-100F fan-cooled black light. Under UV light, the ZL-2C glows a bright greenish-yellow.
Applications for the ZL-15B include inspections on castings, forgings, extrusions and rough machined surfaces in order to find cracks, seams and other discontinuities.
The ZL-15B complies with AMS 2644, ASME B & PV Code, Sec. V, MIL-STD-271, MIL-STD-2132, Boeing BAC 5423 PSD 6-46 or 8-4, General Electric P50YP107, Boeing PS-21202, ASTM E 165, AECL and ASTM E 1417.
ZL-15B fluoresces a bright greenish-yellow under ultraviolet radiation and is safe for use on most engineering and aerospace alloys including aluminum, steel, nickel and titanium. Use of an ultraviolet light source with a peak wavelength of 365 nanometers, such as the Magnaflux ZB-100F fan-cooled black light, is recommended.
Zyglo® ZL-15B penetrant meets OSHA requirements for Class III B liquids due to its high flash point and can be used in open dip tanks.
