≥82.0 It is well known that the iron oxide pigment possesses the best light stability, neverthless the transparent iron oxide with the particle diameter of nanometer lever has stronger ability assimilating the ultraviolet , with the 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, which results in 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 of the surface treatment and possesses the comprehensive medium flexibility, thus can be easily dispersed in various medium.
