Zchek F18W is the blend of fluorescent powder F18 and wetting agent WA. F18 is readily usable with water. The anti-corrosion agents in WA prevent flash rusting of the components.
ZChek F18W 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.
ZChek F18W meets all major industry and NDT specification requirements, including automotive and ASTM standards.
