Introduction
Iron Oxide Red 130: An Inorganic Colored Pigment with Excellent Performance and Wide Applications
Iron Oxide Red 130, chemically known as ferric oxide, has a molecular formula of Fe₂O₃・αH₂O. As an important inorganic colored pigment, it plays an indispensable role in numerous industries. With its stable chemical properties and excellent performance, it has gained wide market recognition.
Chemical Composition
The main component of Iron Oxide Red 130 is Fe₂O₃, with a content of ≥96.0%. This chemical structure endows it with many characteristics. In terms of chemical classification, it belongs to synthetic iron oxide red α-Fe₂O₃, with a pigment index of Pigment Red 101 (77491) and a CAS number of 1309-37-1. Its particles are spherical in shape, which helps the pigment disperse better in various media, thereby exerting its performance advantages.
II. Performance Characteristics
- Excellent hiding power and tinting strength: Iron Oxide Red 130 has high hiding power, which can effectively cover the surface of the coated object, making it show a uniform color. At the same time, it has strong tinting strength, and only a small amount of pigment can give the product a bright and long-lasting color. Whether used in dark or light color systems, it can show excellent coloring effects.
-
Good dispersibility: Due to its spherical particle shape, Iron Oxide Red 130 can be easily dispersed in various media such as coatings, plastics, and rubber, and is not prone to agglomeration. This ensures the quality stability and color uniformity of the product, making the appearance of the produced product more delicate and beautiful.
-
Excellent light resistance and weather resistance: Under sunlight and natural climate conditions, Iron Oxide Red 130 shows extremely high stability. It can resist the erosion of ultraviolet rays, maintain bright colors for a long time, and is not easy to fade. Whether in hot summer or cold winter, in dry or humid environments, it can maintain its original color, which makes it very suitable for coloring outdoor products.
-
Chemical stability: Iron Oxide Red 130 has stable chemical properties. It is insoluble in alkali, stable within a certain acidity range, and can only be completely dissolved in concentrated hydrochloric acid. This characteristic enables it to maintain its own properties in the manufacturing of products in different chemical environments and will not react with other substances to affect product quality.

Application Fields
- Building materials industry: Iron Oxide Red 130 is widely used in the building materials industry. It can be used in colored cement, colored cement floor tiles, colored cement tiles, imitation glazed tiles, concrete floor tiles, colored mortar, colored asphalt, terrazzo, mosaic tiles, artificial marble, and wall painting, etc. By adding Iron Oxide Red 130, these building materials can be endowed with a variety of colors to meet different architectural styles and design needs, while improving the aesthetics and durability of building materials.
-
Coating industry: Iron Oxide Red 130 is an important colorant for various coatings, including water-based interior and exterior wall coatings, powder coatings, oil-based paints (such as epoxy, alkyd, amino and other primers and topcoats), toy paints, decorative paints, furniture paints, electrophoretic paints, and enamel paints, etc. Its excellent hiding power, light resistance, and weather resistance enable the coating to maintain a good appearance and protective performance during use. In addition, iron red primer has anti-rust function, which can replace expensive red lead paint to a certain extent, saving non-ferrous metal resources.
-
Plastic and rubber industry: Iron Oxide Red 130 also plays an important role in coloring plastic and rubber products. It can be used for coloring both thermosetting plastics and thermoplastic plastics, as well as various rubber products, such as automobile inner tubes, aircraft inner tubes, bicycle inner tubes, etc. It can not only bring bright colors to these products but also improve their weather resistance and service life.
-
Other industries: High-purity Iron Oxide Red 130 is also the main base material for powder metallurgy, which can be used for smelting various magnetic alloys and other high-grade alloy steels. At the same time, due to its certain abrasiveness, it can be used as an abrasive in the mechanical field for grinding precision parts to improve their surface finish and accuracy.
