ZYGLO ZL-67B
67B

General Description
Zyglo ZL-67B is a high sensitivity water washable fluorescent
67B
penetrant, used for a wide range of applications.
Designed to exhibit outstanding penetrating characteristics which
provides for maximum reliability in locating surface
surface-open flaws
and discontinuities and is safe to use on most engineering and
inuities
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
ll
drying conditions.
The penetrant fluoresces a bright green-yellow when exposed to
yellow
ultraviolet radiation (UV-A) peak wavelength of 365 nm, and
A)
should therefore be used with a suitable UV source such a the
as
Magnaflux ZB-100F or Magnaflux ZB-100
100-LED.

Applications
ZL-67B is typically used on castings, forgings, semi
67B
semi-rough and
machined surfaces to find cracks, seams, laps, laminations and
porosity.
