MAGNAGLO 410HF
General Description
Magnaglo 14HF and 410HF are oil based ready to use
fluorescent inks for wet method magnetic particle testing.
14HF is the material of choice for aerospace applications giving
clear fluorescent green indications when viewed in a darkened
area under UV(A) of peak wavelength 365nm. A suitable UV
A)
source for such an application is the Magnaflux ZB-100F or
Magnaflux ZB-100-LED.
410HF can be used in similar applications to 14HF. I enhanced
n
It’s
fluorescent green indications and slightly larger particle size
means that a totally darkened inspection area is not always
required.
