MG-410 is an ultra-bright fluorescent magnetic particle powder for locating small, medium, and large discontinuities, as well as slightly subsurface discontinuities such as cracks, inclusions, seams, tears, laps, flakes and welding defects. These particles provide clear, ultra-bright, fluorescent green indications under UV light with minimal background. MG-410 is designed for use in water or oil baths for wet method fluorescent magnetic particle testing. Conditioners for water baths such as WA-2B powder or WC-1 liquid should be used for anti-foaming, corrosion inhibiting, as a wetting agent and to facilitate particle suspension.
Recommended concentration is 1/10 oz./gallon of vehicle (0.75 gram/liter).
