Magnaglo® WB-655 liquid concentrate is used to prepare water-based fluorescent inks for wet method magnetic particle testing. WB-655 gives clear, bright, yellow/green indications when viewed in a darkened area under UV(A) of peak wavelength 365 nm, and offers enhanced corrosion protection. It is a mixture of fluorescent magnetic particles, corrosion inhibitor, wetting agents and foam control additives.

Used in conjunction with suitable magnetising equipment and a UV(A) source, WB-655 will locate fine surface and slightly sub-surface defects such as shrink cracks, welding defects, grinding cracks, quenching cracks, and fatigue cracks.
