Iron oxide pigment is a kind of iron-based oxide refined functional inorganic pigment. With the characteristics of pure color phase, fine particle distribution, excellent weather resistance and strong chemical inertia, it is deeply favored in industrial formula debugging and high-standard coloring fields. Conventional categories include iron oxide red, yellow, black, brown and compound color matching models, which can meet the color design needs of building materials, coatings, rubber, plastics and chemical raw materials.
Through low-temperature oxidation synthesis and surface modification treatment, high-grade iron oxide pigments optimize internal particle structure, effectively improve dispersion and compatibility in organic and inorganic systems. The production process adopts closed circulation water washing and dust-free grinding, which not only ensures stable color difference between batches, but also realizes energy saving and environmental protection in the production process. The product has the characteristics of low oil absorption, easy grinding, no agglomeration and good fluidity, which is convenient for factory batching and automated production.
Its unique performance is reflected in many aspects: stable color development, no floating color and no flowering in the formula; strong anti-ultraviolet and anti-aging ability, which can delay the aging and fading cycle of coatings and building materials; good high-temperature resistance, suitable for high-temperature processing of plastic particles and ceramic firing; non-toxic and tasteless, no harmful substances precipitation, in line with international export environmental protection standards such as REACH and RoHS.
In industrial supporting applications, modified iron oxide pigments show higher adaptability than ordinary pigments. In water-based environmental protection coatings, they maintain stable suspension, not easy to settle, and improve the fullness and flatness of the paint film. In cement concrete products, the color is permeable and uniform, not easy to fade after long-term curing. In rubber and plastic products, they will not decompose and discolor during extrusion and injection molding, and have good processing adaptability. At the same time, it can also be used in artificial leather, paint ink, refractory materials and other auxiliary coloring scenarios.
The key to selecting high-quality iron oxide pigments lies in particle fineness, surface modification effect, batch color difference control and safety environmental protection indicators. Regular manufacturers have complete testing equipment, and each batch will test tinting strength, hiding power, fineness and acid and alkali resistance to ensure stable formula application effect. We supply conventional original color and surface modified iron oxide pigments, support personalized color matching and customized fineness, and meet the procurement needs of domestic industry and foreign trade export.
Different from single ordinary pigment, modified iron oxide pigments take into account coloring performance and processing performance, with wider formula adaptability and longer service life. With the continuous improvement of industrial production standards and export quality requirements, high-quality iron oxide pigments have become an indispensable key raw material in the industrial supply chain.
We focus on the R&D and supply of iron oxide pigments for many years, with sufficient spot inventory and perfect quality inspection system. We can provide technical formula guidance and free sample detection services. Welcome customers from all over the world to consult and negotiate cooperation.
