The FeOEX-Y product series utilizes a pioneering hydrochloric acid leaching process to extract raw materials, yielding reactants with low heavy metal and impurity content. The iron oxide yellow is produced via a liquid alkali neutralization method. Compared to traditional sulfate, nitrate, or mixed acid processes, this technology offers faster reaction kinetics, lower energy consumption, as well as high tinting strength and hiding power. These properties enable reduced pigment usage in coatings, plastics, and cosmetics, contributing to both cost efficiency and environmental sustainability.
