Iron Oxide Brown is an inorganic, iron-based pigment widely used where long-term outdoor color retention and chemical resistance are required. Manufactured through controlled precipitation/calcination (specify process), our grade delivers high tinting power, excellent dispersibility in both aqueous and solvent-based systems, and minimal batch variance.
Premium inorganic iron oxide brown pigment engineered for paints, concrete, pavers and plastics. Consistent shade, low heavy metals, and proven outdoor durability.
architectural paints & coatings, exterior concrete pavers, colored concrete, thermoplastic & masterbatch applications.
Available in multiple standard shades and custom mixes — batch-to-batch shade control down to ΔE < 1 when specified.
Typical uses: exterior architectural coatings, ready-mix concrete colorants, colored paving stones, thermoplastic masterbatch, and industrial coatings. For cosmetics or food-contact uses, request our certified grades and COA.
MOQ: 500 kg standard (regional stock may allow smaller packs). Packaging: 25 kg kraft bags / 500 kg FIBC / bulk tanker (for slurry). Lead time: 2–4 weeks typical — contact for expedited pickup.
Iron Oxide Brown offers excellent exterior durability and color retention. Use recommended dispersant and mill to required tinting strength. For best sheen & hiding, combine with appropriate TiO₂ and extenders.
Our pigments resist alkali environments and deliver stable hues in cementitious systems. We provide target loading tables and case studies for paver projects showing ΔE < 2 over 24 months outdoor exposure.
Suitable for polyolefin masterbatches and thermoplastic coloring. Recommended extrusion temperatures and carrier resins available on request.
Iron oxide brown is typically a mixture of hydrated iron oxides and iron oxide red phases, calcined/processed to deliver a deeper brown shade. Compared to iron oxide red, it offers different chroma and lightfastness — check our TDS for exact composition and L*a*b values.
Typical starting point: 1.0–2.5% by weight of cement. For darker shades or high color intensity, increase loading and adjust mix water/retarders as needed. Conduct lab trials for final formulation.
Our grade tests at 7–8 on the Blue Wool scale and shows excellent alkali resistance in cementitious environments. Independent test reports are available for download.
Anionic high-HLB dispersants for aqueous systems and nonionic dispersants for solvent systems typically perform well. Bead milling to target D50 (<5 µm) provides best tinting & opacity.
Only use cosmetic or food-grade pigments certified for such use. Request our certified grades and COA — standard industrial grades are not automatically suitable for cosmetics/food-contact.
Yes — COA and heavy metal testing reports are available per batch. Contact sales to request documents for a specific lot number.
