Typical Black Iron-Oxide has limited heat-stability, less than 150°C/300°F. To expand the use of Black Iron-Oxide, we post-process the Black Iron-Oxide to form a Black Manganese Ferrite. In doing so the heat stability is increased to applications that reach less than 650°C/1200°F; this enables this pigment to maintain its color in most plastics, coil and powder coatings. CathayTherm F9900MB Black Manganese Ferrite is one of the highest quality Black Manganese Ferrites on the market today. Utilizing premium raw materials processed to exacting specifications, this pigment exhibits easy-dispersing properties and high color strength. Like Black Iron Oxides, F9900MB has excellent lightfastness and chemical resistance. In normal applications it is considered a permanent pigment. While weaker than typical Carbon Black pigments, Black Manganese Ferrites are more compatible with water base systems.
