Product Overview
Iron Oxide Blue 886 is a high-performance inorganic blue pigment produced through the precise blending of PB15:3 (phthalocyanine blue) and PW21 (barium sulfate), engineered for applications demanding maximum weather durability and light fastness. Unlike pure organic phthalocyanine blues that may lack opacity, Iron Oxide Blue 886 delivers superior hiding power with excellent color stability across a wide blue spectrum—from deep navy to bright sky tones. This pigment is the preferred choice for concrete roofing tiles, architectural coatings, cement-based decorative products, and industrial paints where long-term outdoor exposure is non-negotiable. Its weather resistance rating of 5 and light fastness rating of 8 (both full shade and tint) ensure that colored surfaces retain their intended appearance after years of UV and moisture exposure. With a fine powder form, controlled particle size distribution, and ISO 9001-backed batch consistency, Iron Oxide Blue 886 is trusted by manufacturers in over 40 countries for cost-effective, large-scale construction and industrial colorant applications.

Technical Parameter Interpretation
- Weather Resistance (5/5): Iron Oxide Blue 886 achieves the highest weather resistance rating, meaning it withstands prolonged outdoor exposure without significant fading, chalking, or color shift—critical for exterior architectural coatings and concrete products.
- Light Fastness (8/8): A rating of 8 on the Blue Wool Scale (both full shade and tint) indicates outstanding UV stability. Even when tinted down with white, the blue retains its hue under continuous sunlight, outperforming many organic blues in exterior applications.
- Oil Absorption (25-35 ml/100g): This moderate oil absorption range ensures good pigment wetting and dispersion in both solvent-based and water-based paint systems, reducing vehicle demand and optimizing formulation cost.
- pH Value (≥6.0): A near-neutral to slightly alkaline pH provides excellent compatibility with cementitious binders and water-based emulsion systems, minimizing the risk of viscosity drift or flocculation.
- Residue on Sieve ≤0.5% (90μm): The fine particle specification ensures smooth film finish in coatings and consistent color development in plastic masterbatch, with minimal speck contamination.
- Moisture Content ≤1.0%: Low moisture prevents clumping during storage and ensures free-flowing handling in automated dosing systems.
- Color Strength (98-102%): Tight color strength tolerance guarantees batch-to-batch consistency, enabling formulators to achieve reproducible shades without reformulation adjustments.

Frequently Asked Questions — Iron Oxide Blue 886
What makes Iron Oxide Blue 886 different from pure phthalocyanine blue pigments?
Iron Oxide Blue 886 is a composite pigment combining PB15:3 (phthalocyanine blue) with PW21 (barium sulfate), which provides higher opacity, better weather resistance, and lower cost per liter compared to pure phthalocyanine blue. While pure PB15:3 offers high tinting strength and maximum chromatic purity, it can be translucent in mass-tone applications and significantly more expensive per kilogram. Iron Oxide Blue 886 balances color strength with hiding power and durability, making it the more practical choice for mass-toned exterior applications such as concrete coloring, architectural coatings, and industrial paints where coverage and long-term outdoor performance matter more than maximum color saturation.
Can Iron Oxide Blue 886 be used in cement and concrete applications?
Yes, Iron Oxide Blue 886 is specifically designed for cement and concrete coloration. Its pH value of ≥6.0 ensures chemical compatibility with alkaline cement matrices, preventing color shift or efflorescence during curing. The pigment’s excellent weather resistance (5/5) and light fastness (8/8) make it ideal for paving bricks, roofing tiles, concrete blocks, retaining walls, and decorative cement products exposed to full outdoor weather conditions. Recommended dosage is 1-5% by weight of cement, adjusted for desired color intensity. For uniform results, pre-blend the pigment powder with dry cement before adding water.
Is Iron Oxide Blue 886 suitable for plastic masterbatch production?
Yes. Iron Oxide Blue 886 performs well in polyolefin (PP, PE), PVC, and select engineering plastic masterbatch applications. Its heat resistance supports processing temperatures up to approximately 200-240°C, covering typical injection molding and extrusion conditions. The powder form with ≤0.5% sieve residue (90μm) ensures smooth dispersion in polymer melts without visible speck defects. For optimal results, pre-dispersion using a twin-screw extruder at 2-4% pigment loading is recommended before letdown to final concentration. A dispersing aid such as polyethylene wax can further improve color development in thin-wall molded parts.
How does Honor Pigments ensure batch-to-batch consistency for Iron Oxide Blue 886?
Every production batch of Iron Oxide Blue 886 undergoes a comprehensive QC protocol under ISO 9001 certified procedures. Tests include color strength (target 98-102% vs. internal standard), chromatic aberration ΔE ≤0.8, particle size distribution, moisture content, oil absorption, and sieve residue analysis. Full batch records are maintained for a minimum of 3 years for traceability. A Certificate of Analysis (COA) is issued with each shipment, documenting all measured parameters against the product specification. Pre-shipment samples are also available for customer approval before bulk dispatch.
