Fluorescent Magnetic Particle Premix
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.
20B meets all major industry and NDT specification requirements, including automotive, API and ASTM standards.
