Magnaglo® MG-3410 is a dry, free flowing, green magnetic powder which fluoresces bright green under UV black light (wavelength of 365 nanometers). Its bright fluorescent color contrasts with the background of clean metal surfaces when viewed under black light in a darkened area.

MG-3410 is used with water as the suspension vehicle. The powder contains conditioners which improve the magnetic particle suspendibility, mobility and wetting of test part surface. No additional wetting or conditioning agents are required when MG-3410 is used.
