When pigments particle size is less than half-wavelength and fully dispersed in mediators, it will come to light's diffraction with transparent effects, transparent iron oxide pigments with nanometer size are the special material that formed on basis of this principle. Transparent iron oxides retain chemical compositions and crystals of general grade iron oxides, so they own excellent chemical stability, good resistant to acids, alkali, solvents, water and oil. Transparent iron oxide red can be heat resistant for more than 300 degree Celsius.
It's well known that general grade iron oxides own excellent light fastness, while transparent iron oxides with nanometer size have more strong ultraviolet absorption. So, transparent iron oxides are not only excellent light fastness, but also enhanced anti-aging due to ultraviolet absorption. Nanometer size transparent iron oxides own high saturation and tinting strength, because they change general grade iron oxides' absorption and scattering of visible light.
To meet different requirements, Epsilon offers transparent iron oxide pigment powders and transparent iron oxide pigment dispersions. They are widely used in wood coatings, automobile coatings, plastic coatings, metal coatings, architectural coatings, artist colors, high temperature glass ink etc.
