Transparent Iron Oxide Pigment

Transparent Iron Oxide Description
Transparent iron oxide pigment is known as nanometer iron oxide pigment with
primary particle size less than 100nm and typical specific surface area of 80
– 120m2/g. Because its size is smaller than wavelength of visible light (320
– 750nm), diffraction occurs in light irradiation and coating shows
transparency property.
