MAGNAGLO® MG 410 is a fluorescent magnetic powder used to prepare fluorescent inks for high-sensitivity, wet method magnetic particle testing. The ink give clear bright yellow/green indications when viewed under UV(A) light.
To make the inks, you can suspend the powder in either a petroleum-based vehicle (oil) or in water. If water is used, you must add a water bath additive (such as MAGNAFLUX@ WA-1) to improve particle suspendibility and mobility, surface wetting and corrosion inhibition. Mean particle size 14 – 22 µm
