MG 410 is a high-sensitivity fluorescent magnetic particle powder concentrate for detecting very fine to fine surface and slightly subsurface discontinuities. Indications appear an intense yellow-green under UV lighting.
MG-410 is fluorescent powder which can be mixed with either water or oil for a wet-method inspection of metal parts. Conditioners for water baths - such as WA-1 - should be used for anti-foaming, corrosion inhibiting, as a wetting agent and to facilitate particle suspension.
