20B

20B is a highly-sensitive magnetic particle premix powder for locating fine discontinuities in high volume applications, such as forging, casting, stamping and welding. Combining Magnaflux’s best-in-industry 14A magnetic particles, corrosion inhibitors and wetting agents, 20B is an easy-to-use premix for making magnetic particle water bath. The ultra-sensitive 14A particles provide clear, bright, fluorescent green indications under ultra-violet black light for unbeatable inspection quality and accuracy, and the water conditioners provide corrosion protection and complete surface wetting. 20B is a great choice for baths which need to be changed out frequently due to drag-in or heavy-use and is ideal for in-process testing to detect cracks, seams, inclusions, laps, tears and flakes. Premix powder for quick, reliable bath prep High sensitivity Excellent fluorescent contrast Excellent particle mobility Optimized particle size and shape distribution Durable particles Easily dispersed Great concentration consistency Corrosion protection Non-foaming Easy post-testing clean up Good dispersion stability Good surface wetting
