MPI-80 is a premixed, ready-to-use, visible black magnetic particle bath designed for high sensitivity visible magnetic particle inspection. MPI-80 is MPI-80P mixed in Met-L-Glo Carrier #2 and particle flow stabilizers. MPI-80 is often used with WCP-81 white contrast paint to increase contrast for fine flaw detection. It meets the requirements of AMS-3042 and ASTM E-1444 for visible wet method magnetic particle inspection. Aerosols are pressurized with nonflammable, environmentally friendly CO2.

WCP-81 is a special white contrast coating used to create a uniform inspection background for visible magnetic particle inspection. It is sprayed onto the inspection area and allowed to dry. The coating is not effected by the wet method bath fluids, but is easily removed with Met-L-Chek® R-503 or R-504 cleaner.
