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 ultraviolet 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. 20B meets all major industry and NDT specification requirements, including automotive, API and ASTM standards.
