micro-fy Magnetic Powder Concentrate Black Plus is a highly concentrated magnetic powder medium for black/white magnetic particle testing. It is diluted with water at a ratio of 1:40 and, thanks to its increased particle content, offers maximum sensitivity for detecting the finest surface and near-surface cracks in ferromagnetic materials. The increased particle density ensures even clearer, more precise indications, so that even extremely fine
hairline cracks are reliably visible. In combination with a white contrast agent, a particularly clear display effect is created.
