Black iron oxide as a substitute for carbon black
A common black dye for inkjet inks is carbon black, which is an elemental carbon in colloidal form. It is most often sold as a finely ground powder or as a dispersion in a solution with the addition of a surfactant.
By developing the technology for the production of iron (II, III) oxide nanoparticles, Wion Technology has created the possibility of replacing carbon black, opening new paths for improving printing due to the many properties offered by black iron oxides in relation to carbon black:
- Coverage efficiency
- Perfect applicability
- Reduction of the carbon footprint and greenhouse gas emissions
- The economic factor
