Iron Oxide Red is an inorganic red pigment based on α-Fe₂O₃, commonly identified as Pigment Red 101 (PR101, C.I. 77491). It is one of the most widely used iron oxide pigments for industrial coloring because of its combination of lightfastness, weather resistance, chemical stability, and migration resistance.
Iron Oxide Red provides red to reddish-brown shades and is widely used in building materials, concrete, bricks, paints and coatings, plastics, rubber, fiber cement, paper, mortar, paving tiles, roof tiles, ceramics, and industrial coatings.
Compared with many organic red pigments, Iron Oxide Red generally offers stronger long-term stability in outdoor and mineral-based applications. However, its relatively moderate heat resistance and earthy color characteristics should be considered when selecting it for high-temperature plastics or applications requiring highly saturated red shades.
For additional background on hematite, the mineral form associated with α-Fe₂O₃, see Hematite on Wikipedia.
PR101 – Iron Oxide DuraPaint®130 ⬇️TDS
This is a red iron oxide pigment with a deep red shade, good light and weathering resistance, suitable for coatings, plastics, construction materials, and other applications requiring durable red coloration.
PR101 – Iron Oxide DuraPaint®190 ⬇️TDS
This is a red iron oxide pigment with a reddish-brown shade, good light and weathering resistance, suitable for coatings, paints, construction materials, and other applications requiring durable red coloration.
Iron Oxide Red is used across a broad range of industrial applications where durable red coloration and inorganic pigment stability are required.
Iron Oxide Red is widely used for coloring concrete, cement products, bricks, mortar, paving tiles, roof tiles, and other construction materials.
Its excellent lightfastness and weather resistance make it particularly suitable for outdoor architectural products exposed to sunlight, moisture, and changing environmental conditions.
The pigment is used in decorative paints, architectural coatings, industrial coatings, and protective coating systems where stable red coloration and outdoor durability are required.
Its inorganic nature makes it suitable for applications where long-term color stability is more important than achieving the highest possible chroma.
Iron Oxide Red can be used for coloring selected plastic and rubber products where migration resistance, lightfastness, and chemical stability are important.
However, the processing temperature should be carefully evaluated because the current TDS specifies a heat resistance of 300°C.
The pigment can be incorporated into fiber cement, paper, mortar, and other mineral-based materials where stable red coloration is required.
Iron Oxide Red is suitable for ceramic products, paving materials, roof tiles, bricks, and other architectural materials requiring red to reddish-brown shades.
The supplied TDS specifically lists building materials, concrete, bricks, paints and coatings, fertilizers, plastics and rubber polymers, fiber cement, paper, mortar, wood plastic composites, paving tiles, industrial coatings, roof tiles, and ceramic products as recommended applications.
Iron Oxide Red provides excellent resistance to light exposure.
The current TDS gives both DuraPaint®190 and DuraPaint®130 a light resistance rating of 8 in full shade and reduced tinting conditions.
This supports applications such as exterior coatings, concrete products, paving materials, bricks, and roof tiles where long-term color retention is required.
The pigment has a weather resistance rating of 5, supporting its use in outdoor construction materials and coatings.
This property is particularly relevant for concrete, paving products, roof tiles, architectural coatings, and other applications exposed to sunlight and environmental conditions.
Iron Oxide Red achieves a migration resistance rating of 5 in the supplied TDS.
This makes it suitable for selected plastic and rubber applications where pigment migration or bleeding needs to be minimized.
Actual performance should still be evaluated in the target polymer system because resin composition, additives, processing conditions, and pigment concentration can influence migration behavior.
The pigment provides a 4 rating for both acid and alkali resistance.
This characteristic is particularly relevant to concrete, cementitious materials, coatings, and other industrial formulations where the pigment may encounter chemically active environments.
The current grades show a resistance rating of 4 against ethyl acetate, ethanol, and MEK.
This information can be useful when evaluating Iron Oxide Red for coatings, inks, or other systems containing organic solvents. Actual compatibility should be confirmed using the final formulation.
These parameters provide buyers with a consistent technical basis for comparing grades and evaluating formulation requirements.
The current TDS specifies 300°C heat resistance for DuraPaint®190 and DuraPaint®130.
This limits their suitability for high-temperature engineering plastics and processing conditions involving prolonged exposure above the recommended temperature.
For high-temperature plastic applications, buyers should evaluate a pigment grade specifically designed for elevated processing temperatures.
Iron Oxide Red generally produces natural red to reddish-brown shades rather than the highly saturated red shades available from many organic pigments.
For applications requiring bright, high-chroma reds, organic pigments such as Pigment Red 254 or other high-performance red pigments may be more appropriate.
The inorganic nature of Iron Oxide Red gives it a characteristic earthy and mineral-like appearance.
This is advantageous for construction materials and architectural coatings, but may not meet the visual requirements of applications seeking brilliant or very clean red shades.
Different iron oxide grades can produce differences in shade, undertone, particle characteristics, opacity, and dispersion behavior.
Buyers should therefore evaluate the specific commercial grade rather than selecting only according to the generic name “Iron Oxide Red.”
When sourcing Iron Oxide Red, buyers should confirm the following factors before selecting a grade.
Specify whether the pigment will be used in concrete, cement, coatings, plastics, rubber, paper, ceramics, or another industrial system.
Different applications can require different shade, dispersion, chemical resistance, and processing characteristics.
Confirm whether the target shade is red, dark red, reddish-brown, or another specific tone.
Providing a physical color sample, color standard, or target shade reference can help reduce color-matching risk.
For plastics and other heat-processing applications, confirm the actual processing temperature and residence time.
The current grades specify 300°C heat resistance, so applications involving higher temperatures require additional technical evaluation.
For exterior construction materials and coatings, confirm the expected service environment.
The current grades provide a light resistance rating of 8 and weather resistance rating of 5 according to the supplied TDS.
If the product will be used in coatings or formulations containing solvents, buyers should consider the documented resistance to acid, alkali, ethyl acetate, ethanol, and MEK.
Application-specific testing is recommended when the formulation contains high concentrations of solvents or aggressive chemicals.
For international B2B projects, buyers should confirm the required TDS, SDS, CoA, product specifications, and applicable regulatory documentation for the destination market.

Yes. Plastics and rubber polymers are listed among the recommended applications. However, the specified heat resistance is 300°C, so the actual processing temperature must be evaluated before use.
The current TDS specifies 300°C heat resistance for both DuraPaint®190 and DuraPaint®130.
Yes. The supplied TDS gives both grades a migration resistance rating of 5.
Iron Oxide Red generally provides stronger lightfastness, weather resistance, and inorganic durability, while many organic red pigments can provide brighter and more saturated shades.
Iron Oxide Red is based on α-Fe₂O₃ and is classified as Pigment Red 101, while Iron Oxide Yellow is based on α-FeOOH and is classified as Pigment Yellow 42. They provide different shades and are often selected according to the required color and application performance.
For applications requiring brighter or higher-chroma red shades, alternatives may include organic red pigments such as Pigment Red 254 or other high-performance red pigments. For natural mineral red shades and outdoor durability, Iron Oxide Red remains a common choice.
For industrial and export applications, buyers should normally request the relevant TDS, SDS, CoA, product specification, and applicable regulatory or compliance documentation.
