Iron oxide pigments have good weather resistance, high purity, good thermal stability, good compatibility with other components in the application system, can absorb ultraviolet rays, prevent the degradation of the base material, and with low cost, can be widely used in coatings and paints . Due to its strong covering power, strong impermeability to ultraviolet rays and very little water absorption, it can enhance the mechanical strength of the paint film in the paint film, especially its excellent characteristics in adhesion, other anti-rust pigments. Such as red dan, zinc yellow and other mixed use, can enhance the film stability and mechanical strength, is now widely used in various outdoor paints, traffic paints, metal antirust primers and topcoats.
The iron oxide pigments used in coatings and paints include iron red, iron yellow, iron brown, iron black, iron green, mica iron oxide, and transparent iron oxide products, of which iron red products are the most widely used. Through iron is most suitable for automotive topcoats, wood coloring, can coatings, coloring of pharmaceutical packaging and so on.
