Red provides strong contrast on most metal surfaces during dry method magnetic 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.
⦁Sharp, color-contrast indications on high reflective surfaces
⦁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
