| Transparent Iron Oxide Pigment Perfomance |
When pigment particles disperse in the medium, and the diameter of them are smaller than the half wavelength of the light, the diffraction will happen with an effect of transparence tinction. The transparent iron oxide pigment with particle diameter of nanometer-level is exactly a unique material of the kind based on the above theory. The transparent iron oxide possesses sound chemical stability for it maintains the chemical structure and crystal form of the iron oxide pigment,such as acid, alkali, solvent, water and oil resistance,and the transparent iron oxide red even has the heat stability more than 300°C .

It is well known that the iron oxide pigment possesses the best light stability,while the transparent iron oxide with the particle diameter of nanometer lever has stronger ability assimilating the ultraviolet , hence apart from its light stability, the transparent iron oxide pigment can also improve the ageing-resistance ability of all kinds of high polymer by assimilating ultraviolet.

| The transparent iron oxide changes the assimilating and scattering property of the visible portion of the commonness ferric oxide, thus it has a fairly high degree of saturation and tinting strength. Among them, the transparent iron oxide pigment yellow has a dilute color which is quite green, the transparent iron oxide red has a dilute color which is quite orange, and the transparent iron oxide black has a dilute color which is quite blue, which exploits the new space for the application of the transparent ferric oxide. The transparent iron oxide pigment produced by SUNCOM has been performed surface treatment and possesses the comprehensive medium flexibility, thus can be easily dispersed in various medium. |
