iron oxide yellow

Kuncai's unique raw material purification process to get high coloring power, high dispersibility, low metal content, particle size uniformity of iron oxide yellow, unique raw material reaction to produce a unique cylindrical morphology of particles, to provide the product with a high covering power, low oil-absorbing properties.


FeOEX-Y series products adopt Kuncai world's first hydrochloric acid method to extract the raw materials for production, so as to get low heavy metal content and low impurity content of reaction materials. Compared with traditional sulfuric acid, nitric acid and mixed acid process, the iron oxide produced by liquid alkali neutralization process has fast reaction speed, low energy consumption, high coloring power and strong covering power, thus reducing the use of pigments in paints, plastics and cosmetics and saving the environment.
