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.
