While it is possible to chemically synthesize a Brown Iron Oxide, almost all of the synthetic Brown Iron Oxides marketed today are blends of red, yellow and/or black Iron Oxides. Besides being a less expensive production alternative, it also provides a very broad range of colors. All of the outstanding Iron Oxide performance characteristics, including lightfastness and chemical resistance, can also be found in these products.
Cathay Industries F8490 is processed to a lower extent than Cathay’s Best and Better series of Blended Brown Iron Oxides, and that cost savings is passed on to our customers. Customers should expect a lower level of dispersability from Cathay Industries F8490 along with greater lot-to-lot color variation.
