FAQs
What does the grade designation Iron Oxide Green 5605 indicate?
The designation 5605 is an industry color code identifying a specific olive/military green hue range. Naming conventions may vary between manufacturers; CIE Lab measurement is recommended as the reference standard for batch-to-batch color consistency verification.
How does Green Iron Oxide Powder differ from organic green pigments?
Inorganic iron oxide green offers stronger lightfastness, alkali resistance, and weathering durability compared to most organic green pigments. However, its chroma is lower, with tones leaning toward olive and military green rather than bright or vivid greens. Organic pigments such as phthalocyanine green deliver higher saturation but with comparatively reduced alkali resistance and outdoor durability.
How can dispersion of Green Iron Oxide Pigment in water-based systems be improved?
Pre-wetting with polycarboxylate-based dispersants, followed by high-speed dispersion and bead-milling to a fineness of ≤40 μm (Hegman 4–5), effectively improves color uniformity and system stability.
Is Green Iron Oxide Powder suitable for food contact materials?
Standard industrial-grade Green Iron Oxide Powder is not approved for food contact applications. Grades certified under FDA 21 CFR or EU food contact material regulations are required for such use cases, with full compliance verification necessary before application.
Handling and Usage Notes
N1 Wear appropriate dust masks (minimum FFP1) during handling to prevent prolonged inhalation of fine pigment particles.
N2 Processing temperatures exceeding 200°C may cause hue shift; confirm the thermal profile of the formulation system before use.
N3 Batch-to-batch color matching (△E verification) is recommended to ensure production consistency, particularly for architectural and decorative applications.
N4 Store in a dry, cool, ventilated environment; keep sealed to prevent moisture absorption and caking. Shelf life is 24 months under normal storage conditions.
N5 Avoid contact with strong oxidizing agents to prevent chemical reactions that may alter hue stability.

Alkali Resistance and Color Permanence of Green Iron Oxide Pigment in Cementitious Systems
Chemical Synergy and pH Stability
In high-pH environments, such as fresh concrete or cementitious mortars where the pH can reach 12–13, many organic pigments undergo chemical degradation, leading to rapid fading. Green iron oxide pigment is a high-performance composite material engineered by precisely blending inorganic iron oxide yellow (alpha-FeOOH) with stable organic pigments like phthalocyanine blue. Deqing Demi Pigment Technology Co., Ltd. utilizes a specialized manufacturing process that ensures the inorganic component acts as a protective carrier. This structure is inherently resistant to alkaline attack, preventing the saponification or hydrolysis that typically destroys lesser pigments. By maintaining structural integrity within the cement matrix, our green oxide ensures that architectural finishes retain their vibrant hue for decades without chalking or shifting.
Technical Advantages for Architectural Finishes
- Alkali Inertness: The composite pigments from Deqing Demi Pigment Technology Co., Ltd. are chemically inert to calcium hydroxide, the primary byproduct of cement hydration, ensuring no chemical reaction occurs that would alter the pigment's color.
- UV and Weather Resistance: Beyond alkali resistance, our green iron oxide pigment provides exceptional lightfastness. This is critical for exterior architectural finishes that face simultaneous exposure to high-alkalinity substrates and intense solar radiation.
- Uniform Dispersion: Our micronized series allows the pigment particles to integrate evenly within the cement paste, reducing the risk of localized color clusters or "floating," which can lead to uneven fading patterns.
Technical Parameter Comparison: Standard vs. Composite Green Oxide
| Technical Property | Organic Green Dye/Pigment | Composite Green Iron Oxide (Demei) |
| Alkali Resistance (1-5 Scale) | 1 - 2 (Poor) | 4 - 5 (Excellent) |
| pH Stability Range | Narrow (Acidic to Neutral) | Broad (3 - 13) |
| Lightfastness (1-8 Scale) | 4 - 5 | 7 - 8 |
| Fe2O3 Component (%) | 0% | 85% - 90% (Inorganic base) |
| Heat Stability | Low (<150°C) | Moderate to High (Up to 200°C) |

This high-stability series helps reduce overall pigment consumption while caring for the health of employees by minimizing dust during the mixing process.
Technical Factors Influencing Dispersion Speed of Green Iron Oxide Powder in Water-Based Primers
Particle Engineering and Surface Energy
In water-based industrial primers, the dispersion speed of green iron oxide powder is primarily dictated by the interaction between the pigment surface and the aqueous medium. Since green iron oxide is a composite pigment, achieving a rapid and stable "wet-out" is critical. Deqing Demi Pigment Technology Co., Ltd. focuses on controlling the surface tension of our pigments through advanced R&D. Key technical factors include the hydrophilicity of the pigment surface and the presence of any residual salts from the manufacturing process. High-purity pigments with controlled surface energy reduce the induction period during mixing, allowing the particles to transition from dry powder to a fully stabilized suspension more quickly.
Micronization and Aggregate Strength
- Particle Size Distribution: The presence of large aggregates significantly slows down dispersion. Deqing Demi Pigment Technology Co., Ltd. utilizes specialized milling technology for our green iron oxide powder to break down these aggregates into primary particles, ensuring a narrower size distribution.
- Mechanical Sheer Requirements: Micronized series pigments require lower shear force to reach a target Hegman fineness. This not only increases production speed but also protects the integrity of sensitive water-based resins.
- Wetting Agent Compatibility: The chemical treatments applied to our high-performance composite pigments are designed to be compatible with modern non-ionic and anionic dispersants commonly used in industrial primers.
Technical Parameter Comparison: Standard vs. Micronized Green Powder
| Technical Parameter | Standard Green Iron Oxide | Micronized Green Iron Oxide (Demei) |
| Average Particle Size (μm) | 0.4 - 0.9 | 0.1 - 0.3 |
| Hegman Fineness (Grind) | 40μm - 55μm | 10μm - 20μm |
| Oil Absorption (g/100g) | 28 - 35 | 20 - 26 |
| Sieve Residue (45μm) | ≤ 0.5% | ≤ 0.1% |
| Dispersion Speed Score | Standard | Excellent (30% Faster) |
