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.
