Iron Oxide Green is an inorganic green pigment used for durable coloration in construction materials, coatings, plastics, rubber, and other industrial applications.
Unlike conventional single-component iron oxide pigments such as Iron Oxide Red or Iron Oxide Yellow, the DuraPaint®835 formulation listed in the TDS is based on a combination of FeOOH, C₃₂H₁₆CuN₈, and CaCO₃. This composite pigment system provides a green color while combining the durability characteristics required for many industrial applications.
Iron Oxide Green is particularly suitable for applications where lightfastness, weather resistance, migration resistance, and chemical resistance are important. The DuraPaint®835 grade has a specified heat resistance of 170–180°C, making it suitable for applications requiring higher thermal stability than some conventional low-temperature pigment grades.
For additional background on the chemical components associated with this pigment system, see Goethite on Wikipedia, Copper phthalocyanine on Wikipedia, and Calcium carbonate on Wikipedia.
Iron Oxide Green DuraPaint®835 ⬇️TDS
Deep green with good weather and light resistance, suitable for coatings, construction materials, plastics, and other applications requiring durable green coloration..
DuraPaint®835 is recommended for a broad range of industrial applications requiring durable green coloration.
Iron Oxide Green can be used in concrete, cement products, bricks, mortar, paving tiles, roof tiles, and other building materials.
Its strong lightfastness and weather resistance are particularly relevant to architectural products exposed to outdoor conditions.
The pigment is suitable for paints, decorative coatings, industrial coatings, and other coating systems requiring stable green coloration.
Its resistance to light and weathering supports applications where color retention is required during long-term service.
DuraPaint®835 can be used in selected plastics and rubber polymers where migration resistance and thermal stability are important.
With a specified heat resistance of 170–180°C, it can be considered for plastic applications involving higher processing temperatures than low-temperature pigment systems.
The pigment can be incorporated into fiber cement, mortar, and related mineral-based products where durable green coloration is required.
Iron Oxide Green is suitable for wood plastic composites where green or natural outdoor-oriented coloration is required.
The pigment’s light and weather resistance are relevant to WPC products intended for extended environmental exposure.
The TDS also lists ceramic products, roof tiles, paving tiles, and related architectural materials among the recommended applications.
DuraPaint®835 has a light resistance rating of 8 in both full shade and reduced tinting conditions.
This makes it suitable for applications where the green color needs to remain stable under prolonged light exposure, including exterior building materials and architectural coatings.
The product has a weather resistance rating of 5, supporting its use in outdoor applications.
This is particularly relevant to concrete products, paving tiles, roof tiles, exterior coatings, and wood plastic composites that may be exposed to sunlight, moisture, and changing environmental conditions.
DuraPaint®835 has a specified heat resistance of 170–180°C.
This is an important consideration for plastics and other industrial applications involving elevated processing temperatures. The higher thermal stability distinguishes this grade from iron oxide products designed primarily for lower-temperature processing.
The product has a migration resistance rating of 5.
This supports its 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 because resin composition, additives, pigment concentration, and processing conditions can affect performance.
DuraPaint®835 has an acid resistance rating of 4 and an alkali resistance rating of 4.
This is particularly relevant to cementitious materials, concrete, mortar, coatings, and other industrial systems that may encounter acidic or alkaline environments.
The TDS gives the product a resistance rating of 4 against ethyl acetate, ethanol, and MEK.
This information is useful when evaluating DuraPaint®835 for solvent-containing coatings and other organic formulations. Actual compatibility should be confirmed using the final formulation.
DuraPaint®835 is identified in the TDS as a composite system containing FeOOH, C₃₂H₁₆CuN₈, and CaCO₃ rather than a single iron oxide phase.
Because formulation composition can influence color development, dispersion, and compatibility, buyers should evaluate the product in the actual application system before commercial production.
Green can vary significantly in hue, undertone, and saturation.
Buyers requiring a specific green shade should provide a physical sample, color standard, or target reference rather than selecting the product solely according to the generic name “Iron Oxide Green.”
Although the TDS provides an oil absorption range of 25–35 g/100g and a residue on 325 mesh of ≤0.3%, final dispersion behavior depends on the binder, polymer, additives, equipment, and processing conditions used by the customer.
The documented fastness properties provide a useful starting point for product selection, but actual performance can vary with pigment concentration, binder system, processing conditions, and exposure environment.
For demanding applications, laboratory testing using the customer’s final formulation is recommended.
When sourcing Iron Oxide Green, buyers should confirm the following factors before selecting the product.
Specify whether the pigment will be used in concrete, coatings, plastics, rubber, fiber cement, paper, mortar, WPC, ceramics, or another industrial system.
Provide the required shade, undertone, and color reference whenever possible.
This is especially important for green pigments because small changes in hue can significantly affect the final appearance of finished products.
For plastics and other heat-processing applications, confirm the actual processing temperature and residence time.
DuraPaint®835 has a specified heat resistance of 170–180°C, making thermal requirements an important part of grade evaluation.
For exterior applications, confirm the expected level of sunlight and weather exposure.
The current TDS specifies light resistance of 8 and weather resistance of 5, supporting many outdoor construction and coating applications.
For plastics, rubber, and coatings, buyers should evaluate dispersion, migration, chemical compatibility, pigment loading, and processing conditions within the actual formulation.
For international B2B projects, buyers should confirm the required TDS, SDS, CoA, product specifications, and applicable regulatory documentation before commercial purchasing.
For customers comparing different iron oxide colors, the Iron Oxide Pigments category provides access to the broader product range.
Related products include Iron Oxide Yellow, Iron Oxide Red, and Iron Oxide Brown.
As the product range expands, this section can also link to Iron Oxide Black, Iron Oxide Blue, and Iron Oxide Orange.
