Synthetic iron oxides exhibit greater color strength, precise reproducibility of the color shade and higher chemical purity than natural iron oxides and have thus increasingly displaced them. The composition of synthetic iron oxides ensures excellent physiological and ecological compatibility. Our iron oxide-based products are, furthermore, not harmful to the environment or humans.


Kuncai’s iron oxides offer the following performance benefits:
• High purity
• Intense colors
• Strong hiding power
• Low heavy metal content
• Low impurity rate
• Good dispersion propertiest

• Sound thermal stability
• Low oil absorption properties
• Good value in use
