Paint Pigment
iron oxide nanoparticles as a source of black pigment
1. Efficiency of the nanoparticles
Even a small amount of Wion Technology product causes a significant change in a color of a paint, giving it additional functions that characterize iron (II, III) oxide nanoparticles (Fig. 1).
Iron (II, III) oxide in IONSOL 6W and IONSOL 12W products has been adapted to water-based paint formulations with addition of a dispersing agent. It demonstrates stability in systems of stearin and vinyl resins.

2. UVA and Visible Light Protection
Iron oxdie (II,III) nanoparticles are powerful as absorption and protection agent against UVA and visible light radiation. Together with titanium dioxide and zinc oxide, is added to paints to prevent degradation of resins.
3. Markets
INDUSTRIAL PAINTS
iron oxide (II,III) acts as an natural, inorganic pigment for various industrial paints – anticorrosive, decorative, intumescent/fire retardant paints. Combining the pigment with titanium dioxide, color can be varied from black to gray shades.


MAGNETIC PAINTS
iron oxide (II,III) nanoparticles added to basic componenets of a paint, make this paint sensitive to applied magnetic field. Such paints found its purpose in offices where posters and papers can be attached to the wall by simple magnets.
