Product Overview
Iron Oxide Orange 960 is a premium inorganic orange pigment formulated by blending Iron Oxide Red (PR101) with Iron Oxide Yellow (PY42), achieving a warm, natural orange shade with the unmatched durability that only iron oxide chemistry can deliver. Unlike synthetic organic oranges that degrade under UV exposure, this fully inorganic composite maintains its vivid coloration through decades of exterior service.
Construction material producers rely on Orange 960 for decorative brick, terracotta-style roof tiles, stamped concrete, and architectural pavers—applications where color must survive sun, rain, frost, and alkaline cement chemistry without fading or migration. In industrial coatings, its high hiding power enables economical single-coat coverage on structural steel and heavy equipment, while its non-toxic composition meets stringent environmental regulations including heavy-metal-free specifications. For plastics masterbatch, the fine particle distribution and controlled oil absorption (20–30 ml/100g) allow high pigment loading with minimal impact on polymer melt flow, making it equally effective in PE film extrusion, PP injection molding, and PVC profile production. With a bold orange that bridges the gap between muted iron oxide yellows and deep iron oxide reds, Orange 960 gives formulators a distinctive color option without compromising on the lifetime performance guarantees of iron oxide pigment technology.

Technical Parameter Guide
Weather Resistance (5, Full Shade / 5, Tint): Rated 5 out of 5 on the industry standard scale, confirming Orange 960 retains its shade without chalking, cracking, or fading under prolonged outdoor exposure. This performance level is essential for exterior architectural coatings, roof tiles, and façade elements expected to maintain color for 20+ years.
Light Fastness (8, Full Shade / 8, Tint): Blue Wool Scale rating of 8 represents the highest achievable lightfastness. Orange 960’s color remains stable under intense and continuous light exposure, outperforming most organic orange pigments which typically rate 6–7. This makes it the preferred choice for outdoor signage, automotive refinish, and high-end exterior decorative coatings.
Iron Oxide Content (≥88.0% as Fe₂O₃): High purity iron oxide content ensures maximum coloration efficiency per unit weight. The ≥88.0% specification is a key quality indicator—higher oxide content directly correlates with stronger tinting strength and better hiding power, reducing the pigment loading required to achieve target color depth.
Oil Absorption (20–30 ml/100g): This relatively low oil absorption indicates efficient pigment wetting with minimal binder demand. In paint formulations, low oil absorption allows higher pigment volume concentration (PVC) without excessive viscosity, translating to more economical formulations with better coverage per liter.
pH Value (3–7): The slightly acidic to neutral pH range is characteristic of high-purity synthetic iron oxides and ensures excellent compatibility with a broad range of resin systems. This pH profile prevents unwanted interactions with acid-catalyzed coating systems while remaining non-corrosive to processing equipment.
Density (0.4–0.6 g/cm³): The low bulk density facilitates easy handling, volumetric dosing accuracy, and efficient transportation. This lightweight characteristic also contributes to favorable coverage economics—more volume per kilogram compared to denser inorganic pigments.
Residue on Sieve, 90μm (≤0.3%): Minimal oversize particles guarantee smooth film surfaces in thin-coat applications and prevent screen clogging during masterbatch extrusion. This specification is particularly important for high-gloss industrial finishes where surface defects from coarse particles are unacceptable.
Water Soluble Content (≤0.3%): Exceptionally low water-soluble salts prevent osmotic blistering in protective coatings and eliminate electrical conductivity concerns. This premium specification exceeds the ≤1.0% standard for general-purpose iron oxides, making Orange 960 suitable for high-specification anticorrosion primer systems.
Color Strength (95%–105%): Production batches are controlled within ±5% of the standard tinting strength, ensuring customers can maintain consistent color in their finished products without reformulation. This tight tolerance is critical for brand-color architectural products and repeat-order manufacturing.
Chromatic Aberration ΔE (≤1.0): A delta E of ≤1.0 means batch-to-batch color difference is invisible to the human eye (threshold of perception is ΔE ≈1.0–2.0). This specification guarantees seamless continuity across production lots—essential for large-scale construction projects and industrial OEM supply chains.

Frequently Asked Questions — Iron Oxide Orange 960
Why choose Iron Oxide Orange 960 over organic orange pigments for exterior applications?
Iron Oxide Orange 960, a composite of PR101 (Iron Oxide Red) and PY42 (Iron Oxide Yellow), offers fundamentally superior exterior durability compared to organic orange pigments such as PO13, PO34, or PO36. While organic oranges provide high chroma initially, they typically degrade within 2–5 years of outdoor exposure through photochemical breakdown. Orange 960 maintains its shade integrity for 20+ years with a weather resistance rating of 5 and light fastness of 8—the highest achievable scores. Additionally, its fully inorganic composition eliminates heavy metal concerns (lead-free, cadmium-free, chromate-free), meeting global regulatory requirements including REACH and RoHS. For construction materials, industrial coatings, and any application where long-term color retention is non-negotiable, Orange 960 is the technically superior and economically sound choice.
How should Iron Oxide Orange 960 be dispersed for optimal color development?
Iron Oxide Orange 960 requires mechanical shear for full color development. For paint and coating applications, a high-speed disperser at 15–20 m/s tip speed for 15–20 minutes achieves optimal dispersion. In plastics, twin-screw extrusion with L/D ratio ≥32:1 ensures complete pigment distribution within the polymer matrix. The pigment’s low oil absorption (20–30 ml/100g) and controlled particle shape facilitate rapid wet-out. For construction materials such as concrete and mortar, pre-blending with fine aggregate or using a pigment slurry preparation method significantly improves color uniformity. If agglomerates persist, a bead mill pass at moderate intensity resolves any remaining dispersion issues without altering the pigment’s primary particle characteristics.
Is Iron Oxide Orange 960 suitable for food contact or toy safety applications?
Iron Oxide Orange 960 is manufactured from high-purity synthetic iron oxides and contains no heavy metals (lead, cadmium, mercury, or hexavalent chromium). Its non-toxic profile makes it suitable for applications requiring compliance with toy safety standards (EN 71-3, ASTM F963) and indirect food contact regulations. The low water-soluble content (≤0.3%) further supports migration testing compliance. However, specific end-use certification depends on the complete formulation and processing conditions. We recommend customers submit finished articles for final compliance testing and are happy to provide detailed compositional declarations to support regulatory submissions.
What are the advantages of Iron Oxide Orange 960 for concrete paver and roof tile manufacturing?
Orange 960 delivers four key advantages for concrete product manufacturers. First, its alkaline stability (resistant to pH 12–13 cement chemistry) ensures the orange shade remains true throughout curing and decades of service—unlike organic pigments that bleach in alkaline environments. Second, the high iron oxide content (≥88%) provides strong tinting strength at economical dosage rates of 2–4% by cement weight. Third, excellent UV and weather resistance (both rated maximum) prevents the chalky, faded appearance that inferior pigments develop after 3–5 years. Fourth, the pigment’s irregular particle shape mechanically interlocks within the cement matrix, minimizing efflorescence migration and ensuring uniform color throughout the product cross-section rather than just surface coloration.
