MG 410

Fluorescent Magnetic Particles

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.

  • Clear, ultra-bright indications under UV light
  • Provides excellent discontinuity definition
  • Can be suspended in water or oil vehicle
  • Minimal background
  • High sensitivity
  • Excellent fluorescent contrast
  • Excellent particle mobility
  • Optimised particle size distribution
  • Durable particles
  • Easily dispersed
