Black/White MPI: Comparison of oil- and waterbased suspensions
Good magnetic particle suspensions – such as PFINDER 251 – with an oil-based carrier are characterized by a high mobility of their black particles. Quick and stable indications with a strong contrast and a high sensitivity are the result and of fundamental importance for the users. PFINDER has succeeded in reaching this quality with a water-based carrier now: PFINDER 240 – a non-hazardous black magnetic particle suspension, not classified acc. GHS. In addition the aerosol spray can of PFINDER 240 with the same volume contains 20% more suspension compared to conventional products.
