Product Description

Wuchang Pigment has been engaged in the production, R&D and sales management team of high performance iron oxide series products for more than 20 years. The senior managers are all from domestic iron oxide pigments production enterprises. At present, there are more than ten high-performance iron oxide inventions. The high-temperature resistant zinc iron yellow, coated iron yellow, ferromanganese black, low arsenic red and red pigments for lithium batteries have been produced in large quantities. At the same time, the food-grade products developed by the company have passed strict European Union testing, and all heavy metal indicators are superior to industry and food-grade control standards.
Food grade iron oxide is an important inorganic color pigment, which has high covering power, strong coloring power, good dispersibility, light resistance and weather resistance, and has broad market space.

Use of organic pigments:
Organic pigment is an insoluble organic substance, which is usually added to the substrate in a highly dispersed state to make the substrate colored. Organic pigments are widely used in the colouring of inks, paints, coatings, synthetic fibers, as well as textile pigment printing, plastics, rubber, leather and so on. The output of organic pigments accounts for about a quarter of the total output of dyes.
