Iron Oxide Brown is an inorganic brown pigment produced from a combination of iron oxide phases, commonly including α-Fe₂O₃, α-FeOOH, and Fe₃O₄. It provides natural brown to reddish-brown shades and is widely used in industrial applications where durable coloration, weather resistance, and chemical stability are required.
Unlike a single-phase iron oxide pigment such as Iron Oxide Red or Iron Oxide Yellow, Iron Oxide Brown can combine different iron oxide components to produce characteristic brown shades and application-specific performance.
Iron Oxide Brown is commonly used in building materials, concrete, bricks, paints and coatings, plastics, rubber, fiber cement, paper, mortar, paving tiles, roof tiles, wood plastic composites, and ceramic products.
For additional background on the iron oxide minerals associated with this pigment system, see Hematite on Wikipedia, Goethite on Wikipedia, and Magnetite on Wikipedia.
Iron Oxide Brown DuraPaint®610 ⬇️TDS
This is a brown iron oxide pigment with a warm brown shade, good light and weathering resistance, suitable for coatings, plastics, construction materials, and other applications requiring stable brown coloration.
Iron Oxide Brown DuraPaint®660 ⬇️TDS
This is a brown iron oxide pigment with a warm, earthy brown shade, good light and weathering resistance, suitable for coatings, plastics, construction materials, and other applications requiring stable brown coloration.
Iron Oxide Brown is used where natural brown coloration and the durability associated with inorganic iron oxide pigments are required.
Iron Oxide Brown is widely used in concrete, cement products, bricks, mortar, paving tiles, roof tiles, and other construction materials.
Its stable color and weather resistance make it suitable for architectural products exposed to outdoor conditions.
The pigment can be used in decorative paints, architectural coatings, industrial coatings, and other systems requiring brown or earth-tone coloration.
It is particularly suitable for applications where natural mineral colors are preferred over highly saturated organic shades.
Iron Oxide Brown can be used for coloring selected plastics and rubber polymers where migration resistance, lightfastness, and weather resistance are important.
For thermoplastic applications, grade selection is especially important because DuraPaint®610 and DuraPaint®660 have substantially different heat resistance ranges.
The pigment is suitable for wood plastic composites where brown and natural wood-tone coloration is required.
The inorganic pigment system can provide a durable color appearance suitable for outdoor-oriented composite materials.
Iron Oxide Brown can be used in fiber cement, paper, mortar, and related mineral-based products requiring stable brown coloration.
The pigment is also recommended for ceramic products, paving materials, roof tiles, and other architectural applications.
The supplied TDS 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 among the recommended applications.
Both DuraPaint®610 and DuraPaint®660 provide a light resistance rating of 8 in both full shade and reduced tinting conditions.
This supports applications in exterior construction materials, architectural coatings, paving products, roof tiles, and other products exposed to sunlight.
Both grades have a weather resistance rating of 5.
This makes Iron Oxide Brown suitable for outdoor building materials, coatings, paving products, and other applications where long-term exposure to sunlight and weather conditions is expected.
Heat resistance is the most significant performance difference between the two grades.
DuraPaint®610: 170–180°C
DuraPaint®660: 60–80°C
This gives buyers a clear grade-selection criterion. DuraPaint®610 is more suitable when the formulation or processing system requires higher thermal stability, while DuraPaint®660 should be considered primarily for lower-temperature applications.
Both grades have a migration resistance rating of 5.
This supports their use in selected plastic and rubber applications where pigment migration or bleeding needs to be controlled.
Actual migration behavior should still be evaluated in the final polymer formulation.
Both grades provide an acid resistance rating of 4 and an alkali resistance rating of 4.
This is relevant to construction materials, coatings, cementitious systems, and other industrial formulations that may encounter acidic or alkaline environments.
Both grades show a resistance rating of 4 against ethyl acetate, ethanol, and MEK.
This provides useful technical information when evaluating the pigment for solvent-containing coatings and other organic formulations. Actual compatibility should be confirmed with the final formulation.

The two available grades should not be treated as thermally equivalent.
DuraPaint®610 provides 170–180°C heat resistance, while DuraPaint®660 is specified at only 60–80°C.
For plastic and other heat-processing applications, buyers should select the grade according to actual processing temperature rather than choosing solely based on the generic name “Iron Oxide Brown.”
Iron Oxide Brown produces natural, earthy brown shades associated with mineral pigments.
It may not be the best choice for applications requiring exceptionally bright, clean, or highly saturated brown coloration.
Because Iron Oxide Brown contains multiple iron oxide phases, the final shade can be influenced by pigment composition, particle characteristics, concentration, binder system, and other formulation factors.
Color matching should therefore be performed using the actual application system.
Although DuraPaint®610 can withstand higher temperatures than DuraPaint®660, buyers should still confirm the actual processing temperature, residence time, and formulation conditions before commercial production.
When sourcing Iron Oxide Brown, buyers should pay particular attention to grade selection and processing temperature.
Confirm whether the pigment will be used in concrete, coatings, plastics, rubber, wood plastic composites, ceramics, paper, or another industrial system.
This is especially important for plastics.
If the application involves elevated processing temperatures, DuraPaint®610 should be evaluated because its specified heat resistance is 170–180°C, while DuraPaint®660 is specified at 60–80°C.
Specify whether the desired color is reddish brown, dark brown, warm brown, or another earth-tone shade.
A physical color sample or reference standard is recommended for accurate matching.
For exterior products, confirm the required light and weather resistance.
Both grades provide light resistance of 8 and weather resistance of 5 according to the current TDS.
For plastics and rubber, buyers should evaluate dispersion, migration, processing temperature, polymer compatibility, and pigment loading within the actual formulation.
For international B2B projects, buyers should confirm the required TDS, SDS, CoA, product specifications, and applicable regulatory documentation.
For other iron oxide colors, buyers can review the Iron Oxide Pigments range.
Related products include Iron Oxide Yellow, Iron Oxide Red, and, as the product range expands, Iron Oxide Black, Blue, Green, and Orange.
