Ultra-fine iron oxide

The ultra-fine iron oxide pigments are equipped with the excellent performance of normal iron oxide pigments, the fineness D50 grinded is around 1 um and the tinting power is improved by 15%~20%. Different additives are added according to different usages, which reduce the surface traction in the medium and make the pigment easily to be dispersed and greatly improve the storage stability of the paint.
The products are exported to different countries and the quality has met advanced world standard.
The easily dispersed iron oxide pigment is processed after surface modified treatment to normal iron oxide pigment. The product has the dispersion performance that cant be compared by normal pigment, which can reduce the grinding time, greatly improve the efficiency and reduce the cost. Moreover, it can improve the hardness of the coating film in the coating and improve the storage stability. It will improve the solution of the concrete and improve the hardness and intensity.
Application The ultra-fine products can be used as stain for high grade paint, coating, plastic, rubber, chemical constructional materials and constructional cement.
The easily dispersed products can be used as stain for coatings, constructional structures, concrete products, ceramic, rubber, plastics, and etc.
