Wuchang pigments introduce ultrafine iron oxide particles < 17um, Heigman fineness > 7um; better color stability and brighter color between batches; superior dispersion, greatly shorten the dispersion time, improve production efficiency; higher coloring intensity, can reduce the amount of pigm......
