iron oxide pigments are a class of coloring pigments based on iron oxides, mainly including iron oxide red, yellow iron oxide, iron oxide black, and iron oxide brown. These pigments are widely used in multiple industries due to their excellent dispersibility, lightfastness, and weather resistance. Below is a detailed introduction to iron oxide pigments in English:

Basic Properties

• Main Composition: Iron oxides, such as iron oxide red (Fe₂O₃), yellow iron oxide (FeO(OH)), and iron oxide black (Fe₃O₄).
• Characteristics: They exhibit good dispersibility, lightfastness, weather resistance, chemical stability, and physical fastness. Additionally, iron oxide pigments demonstrate excellent UV opacity and low water absorption, enhancing the mechanical strength, particularly adhesion, of paint films.

Application Fields

1. Building Materials: Used for wall painting, artificial marble, terrazzo flooring, and coloring silicate products. Iron oxide pigments are particularly prominent in cement-based building materials due to their resistance to sunlight exposure, weathering, migration, and having no detrimental effects on cement properties.
2. Paints and Coatings: Widely applied in various types of paints and coatings for coloring and protection, including alkyd resins, aminoalkyd resins, vinylidene chloride resins, polyurethanes, nitrocelluloses, polyesters, electrophoresis paints, primers, enamel paints, pencil paints, ready-mixed paints, baking paints, antirust paints, and floor paints.
3. Plastics and Rubber: Serve as coloring agents and fillers in plastic and rubber products, enhancing color, durability, and aging resistance. For instance, iron oxide red without copper, manganese, or other heavy metal ions can prevent rubber aging in aviation tires.
4. Other Fields: Also used in inks, ceramics, cosmetics, pharmaceutical coloring, photocopying materials, catalysts, electronics, and magnetic recording materials.
