Iron oxides are CATHAY INDUSTRIES’ core business. As the third largest iron oxide manufacturer in the world, CATHAY INDUSTRIES provides a wide range of iron oxide pigments from economical grades for construction applications, to high-quality CATHAYCOAT™ for top coating, and the highest-purity CATHAYPURE™ for cosmetics.


CATHAYPURE™ is the series of high-purity iron oxide pigments with extremely low heavy metal content. CATHAYPURE™ is tailor-made for high-purity applications such as cosmetics, medicines and food packaging. In order to respond to different purity requirements, CATHAYPURE™ is differentiated into two series, "E" and "Z" grades.


CATHAYCOAT™ is CATHAY INDUSTRIES’ premium range of iron oxides. It’s made for top coating and fine-quality products like paints, plastics and paper. CATHAYCOAT™ can be divided into four subcategories, from the most-premium micronized "A" grades and LV grade, to standard "S" grades, and more economical "C" grades and Primer grades.


CATHAY INDUSTRIES provides a full range of colors to the construction industry for asphalt, cement, tiles and other materials. Our construction grades are clustered into five series:

FERROTINT™ - basic pigment powder
FLOWTINT™ - free-flow pigment powder
CATHAYGRAN™ - granular pigments for automated dosage machines
Masterbatches - pelletized pigment for asphalt coloring


CATHAYMAG™ is a special range of pigments that are produced at our U.S. site dedicated to pigments with the highest purity requirements. These Magnetic Iron Oxides are offered for toners, magnetic inks, transfer ribbons, and other applications that require magnetic properties.
