Colored, Non-fluorescent Magnetic Particles #2 Yellow provides strong contrast on most metal surfaces during dry method mag particle testing in visible light. It is ready-to-use for visible light flaw detection of surface and slightly subsurface discontinuities in ferrous metals. It can be used in a powder blower or shaken from a bottle during magnetization, and blown off while current is still being applied. On material with a high magnetic retentivity, indications can still be formed after the current has been turned off. Benefits Sharp, color-contrast indications on high reflective surfaces Ready-to-use Good particle buildup for quick detection Highly refined for optimal particle shape and size combination Minimal dust build-up Does not require a black light or darkened inspection area Magnavis® Dry Method Non-Fluorescent Magnetic Powders are ready to use, free flowing, general purpose magnetic powders designed to produce, superior indications of surface and slightly subsurface discontinuities in ferrous materials.
