ZL-60C

Zyglo® ZL-60C is a general purpose water washable fluorescent penetrant, used for a wide range of low to medium sensitivity applications. They are typically used on castings, forgings, rough and machined surfaces to find cracks, seams, laps, laminations and porosity. It exhibits outstanding penetrating characteristics which provides for maximum reliability in locating surface-open flaws and discontinuities and are safe to use on most engineering and aerospace alloys including aluminium, steel, nickel and titanium. The penetrant has been formulated to give excellent controlled washability over a wide temperature range and variable dwell times and will produce stable fluorescent indications under normal drying conditions. The penetrant fluoresce's a bright green-yellow when exposed to ultraviolet radiation (UV-A) peak wavelength of 365 nm. Pratt & Whitney approved
