Short Description:
Widely used in paints, pigments, coatings, plastics, ceramics, rubber, paper and other industries.
Green Iron Oxide Powder
Green Iron Oxide Powder is an inorganic synthetic pigment typically produced by blending iron oxide yellow (FeOOH) with iron oxide black (Fe₃O₄) in controlled ratios, or through co-precipitation of iron and chromium salts, yielding hues from olive green to deep military green.
A widely used grade, Iron Oxide Green 5605, delivers a distinctive olive/military green tone suitable for construction coloring, industrial coatings, and specialty applications. Green Iron Oxide Pigment provides long-term color stability under UV exposure, alkaline environments, and outdoor weathering conditions. The product is free from restricted heavy metals, complying with REACH and RoHS regulations.
Iron Oxide Green Pigment features controllable particle size, good dispersibility, and compatibility with aqueous, solvent-borne, and dry powder systems, making it applicable across construction materials, industrial coatings, plastics, and rubber.

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.
