CATHAYMAG™ Black MO4238

Product OverviewTypical Properties

MO4238 is a synthetic black magnetic iron oxide (magnetite, ferrosoferric oxide) specifically designed for MICR (Magnetic Ink Character Recognition) applications.

MO4238 is a specialty analog of its predecessor (MO4232) and is distinguished by its smaller particle size and higher coercivity. MO4238 formulates readily in MICR inks and toners requiring high gloss and high remanent magnetization. MO4238 complies with the RoHS regulations.
