Product Information

Iron oxide produced by extraction process was pioneered by Kuncai, ensuring the quality stability of raw materials and meeting the requirements of low heavy metal content. The reaction adopts the process of liquid alkali neutralization and direct air chlorination, which improves the reaction rate by 50%. The product has low heavy metal content, which can be used in food and cosmetic products. After special treatment, the production wastewater can be directly used in the chlor-alkali industry, achieving the whole process cycle, energy saving and emission reduction, and realizing environmentally sustainable development and moving towards a green economy.


 Product Characteristics

Iron oxide pigments exhibit rich colors, broad color spectrum, high hiding powel and strong tinting strength. The main colors are red, yellow and black, and by mixing, it is also possible to obtain a range of composite pigments with orange, brown and green.


Main features

lron oxide pigments have excellent resistance to light, weathering, acids, alkalis and solvents, but also have the characteristics of non-toxicity, making them widely used in building materials, coatings, inks, plastics, ceramics, paper making and magnetic recording materials.
