Micronized Iron Oxide Black is a fine-particle inorganic black pigment based on Fe₃O₄, designed for industrial applications requiring consistent black coloration, controlled particle size, and stable pigment performance.
Fineland Chem offers DuraPaint®318M and DuraPaint®395M as Micronized Iron Oxide Black grades, both classified as Iron Oxide Black (C.I. 77499). Both grades have an Fe₂O₃ content of ≥95%, a specified particle size of 0.2 μm, and a bulk density of 0.4–0.6 g/cm³.
The micronized grades are suitable for building materials, concrete, paints and coatings, plastics, rubber polymers, fiber cement, paper, mortar, wood plastic composites, paving tiles, industrial coatings, roof tiles, and ceramic products.
For general information about magnetite and iron oxide materials, see Magnetite on Wikipedia and Iron oxide on Wikipedia.
Micronized Iron Oxide Black DuraPaint®318M ⬇️TDS
Recommended for Building materials, concrete, bricks, paints & coatings, fertilizers, plasticsandrubber polymers, fiber cement, paper, mortar, wood plastic composites, paving tiles, industrial coatings, roof tiles, ceramic products.
Micronized Iron Oxide Black DuraPaint®395M ⬇️TDS
Recommended for Building materials, concrete, bricks, paints & coatings, fertilizers, plasticsandrubber polymers, fiber cement, paper, mortar, wood plastic composites, paving tiles, industrial coatings, roof tiles, ceramic products.
Micronized Iron Oxide Black is suitable for a wide range of industrial applications where fine-particle black pigmentation and durable color performance are required.
Micronized Iron Oxide Black can be used in concrete, cement products, bricks, mortar, paving tiles, roof tiles, and other construction materials requiring black or dark coloration.
Its lightfastness and weather resistance are relevant to products exposed to outdoor environments.
The pigment can be used in decorative paints, architectural coatings, and industrial coatings requiring stable black coloration.
The fine particle size of 0.2 μm can be considered when evaluating dispersion and color development in the selected coating system.
Micronized Iron Oxide Black can be used in selected plastics and rubber polymers where black coloration, migration resistance, and controlled particle size are required.
However, the specified heat resistance of 60–80°C should be carefully considered when selecting this grade for thermally demanding plastic-processing applications.
The pigment is suitable for fiber cement, mortar, and other mineral-based products requiring consistent black coloration.
Micronized Iron Oxide Black can be considered for WPC products requiring black or dark coloration.
Its light resistance of 8 and weather resistance of 5 are relevant to outdoor applications.
The TDS also lists paper and ceramic products among the recommended applications, allowing the pigment to be evaluated across different industrial coloration systems.
Both DuraPaint®318M and DuraPaint®395M have a specified particle size of 0.2 μm.
This fine particle size is the defining characteristic of the micronized grades and should be considered when evaluating dispersion, color development, surface appearance, and processing behavior.
Both grades have an Fe₂O₃ content of ≥95%.
This provides a clear composition specification for buyers evaluating pigment quality and grade consistency.
Both grades have a light resistance rating of 8 in full shade and reduced tinting conditions.
This supports applications where black coloration needs to remain stable during prolonged exposure to light.
The products have a weather resistance rating of 5.
This is relevant to concrete, paving tiles, roof tiles, WPC, exterior coatings, and other outdoor applications where long-term color stability is important.
Both grades have a migration resistance rating of 5.
This makes them suitable for consideration in plastics and rubber applications where pigment migration or bleeding needs to be controlled.
Actual migration performance should be verified in the target polymer formulation.
Both grades have acid and alkali resistance ratings of 4, together with resistance ratings of 4 against ethyl acetate, ethanol, and MEK.
These properties allow the pigments to be evaluated across mineral, coating, plastic, rubber, and other industrial formulation systems.
DuraPaint®318M and DuraPaint®395M have a specified heat resistance of 60–80°C.
Therefore, these micronized grades are not suitable for applications requiring prolonged exposure to high processing temperatures. Buyers working with high-temperature plastics or thermal-processing conditions should consider a heat-resistant iron oxide black grade instead.
The 0.2 μm particle size can provide advantages in selected formulations, but fine particles still require appropriate dispersion conditions.
Dispersion equipment, processing method, pigment concentration, binder or polymer system, and additives should be evaluated together.
The final black appearance can vary according to pigment loading, binder or polymer system, dispersion quality, and the presence of other pigments or additives.
For accurate color matching, buyers should provide a target color standard or physical sample.
The two grades have different moisture specifications.
DuraPaint®318M has a maximum moisture content of ≤1.0%, while DuraPaint®395M has a maximum of ≤1.5%. Buyers with strict moisture requirements should specify the preferred grade when requesting a quotation or sample.
When sourcing Micronized Iron Oxide Black, buyers should confirm the following factors.
If fine particle size is important to the formulation, confirm the required particle-size range and measurement method.
Both DuraPaint®318M and DuraPaint®395M have a specified particle size of 0.2 μm.
Fineland Chem offers two grades:
DuraPaint®318M: moisture ≤1.0%
DuraPaint®395M: moisture ≤1.5%
The other listed physical and fastness properties are essentially the same according to the current TDS specifications.
Specify whether the pigment will be used in concrete, coatings, plastics, rubber, fiber cement, paper, mortar, WPC, ceramics, or another industrial application.
For plastics and rubber, buyers should provide the actual processing temperature and residence time.
The specified heat resistance of these grades is 60–80°C, so they should not be selected for applications requiring high-temperature pigment stability.
For high-temperature applications, customers can also evaluate Heat Resistance Iron Oxide Black as an alternative grade if available for the required application.
For coatings, plastics, rubber, and other formulated systems, buyers should provide information about the dispersion method, equipment, pigment loading, and binder or polymer system.
For exterior applications, confirm the expected sunlight and weather exposure.
Both grades have light resistance of 8 and weather resistance of 5, supporting their evaluation in outdoor construction and coating applications.
For international B2B projects, buyers should confirm the required TDS, SDS, CoA, product specifications, and applicable regulatory documentation before commercial purchasing.
For customers comparing micronized and conventional grades, Fineland Chem offers a range of standard iron oxide pigments, including Iron Oxide Yellow, Iron Oxide Red, Iron Oxide Orange, Iron Oxide Blue, Iron Oxide Green, and Iron Oxide Brown.
These conventional grades allow buyers to compare pigment color, grade characteristics, processing requirements, durability, and application suitability.
