Applications of Pigment Blue 27 in Industrial Manufacturing

Pigment Blue 27, a ferric ammonium ferrocyanide class pigment, remains integral in multiple large-scale manufacturing processes demanding stable, bright, and weather-resistant blue coloration. As an established chemical pigment producer, we supply material that meets strict quality expectations essential for achieving consistent formulation results in downstream industrial settings.

1. Printing Inks for Security and Banknotes

Printing ink manufacturers depend on this pigment for its resistance to diluted acids and alkalis, high color fastness, and reliable reproducibility, especially in security applications. During formulation of inks for currency, legal documents, and certificates, precise control of pigment dispersion and color tone ensures anti-counterfeiting functionality and regulatory compliance in national mints and secure print facilities.

Industry compliance standards

• ISO 2846-1:2017 (Color and transparency for offset inks)
• ISO 12498 (Security printing standards)
• EN 71-3 (Migration of certain elements in printed materials)
• RoHS 2011/65/EU (Restriction of Hazardous Substances)

Typical usage ratio

• 1% to 6% w/w in ink concentrate, adjusted for color intensity and substrate; security inks often use the higher range for visual and machine-readable features.

Downstream process integration

• Pigment disperses in ink vehicles during the premix and milling stage; intensive mixing ensures homogeneous particle size for screen and intaglio printing applications.

Final product types

• Banknote inks, passport and ID card inks, legal security document prints, check printing inks

2. Coatings for Consumer Electrical Appliances

Major appliance coating producers leverage this pigment for stable blue shades on enameled and powder-coated surfaces, benefiting from resistance to heat, light, and cleaning chemicals. The pigment accommodates both water-based and solvent-borne coating systems, delivering consistent batch-to-batch color suitable for visible and internal components of home electrical devices.

Industry compliance standards

• RoHS 2011/65/EU (Material safety for electronics)
• GSB ST 663 (Guidelines for powder coatings)
• ISO 12944 (Corrosion protection for steel structures)
• REACH Regulation (EC) No 1907/2006

Typical usage ratio

• 0.3% to 3.0% in total coating solids; the ratio depends on the desired shade and film thickness, with lower percentages common in topcoats and higher for effect or base layers.

Downstream process integration

• Dispersion occurs during grinding or high-speed mixing of resin, additives, and fillers; incorporated before let-down in both continuous and batch coating lines, followed by spray or dip application.

Final product types

• Blue side panels of refrigerators and washing machines, panel coatings for consumer electronics, protective housings, appliance trims

3. Plastic Masterbatch and Compounding

Polymer processing and masterbatch producers use Pigment Blue 27 to provide vivid, non-migrating coloration in PVC, polystyrene, polyolefins, and engineering plastics. Its high dispersion capacity and low volatility at typical compounding temperatures support uniformity in both opaque and translucent plastics with strict color performance metrics.

Industry compliance standards

• EN 71-3 (Toy safety for colored plastics)
• FDA 21 CFR 178.3297 (Pigment use in food contact plastics – limited applications)
• REACH Annex XVII (Restricted substances in plastics)
• ISO 9001:2015 (Quality management for compounding facilities)

Typical usage ratio

• 0.05% to 1.5% in the total polymer matrix; color depth, end-use, and polymer type determine the level—concentrated batches may use higher percentages intended for further dilution.

Downstream process integration

• Incorporated at the hopper or pre-mixed with carrier resins before extrusion or injection molding; twin-screw extruders disperse pigment into thermoplastic granules or pellets.

Final product types

• Colored cable insulation, blue PVC pipes, consumer plastic casings, automotive clips and fasteners

4. Artist and School Supplies Manufacturing

The pigment’s intense bright blue and good lightfastness make it suitable for formulating high-performance watercolors, poster paints, and crayons. Producers in this segment demand low impurity levels and batch consistency to meet both safety standards and chromatic integrity, especially in products for children and educational use.

Industry compliance standards

• EN 71-7 (Safety of finger paints)
• ASTM D4236 (Labeling art materials for chronic health hazards)
• ISO 8124-3 (Migration of certain elements in toys)
• CPSIA (U.S. Consumer Product Safety Improvement Act)

Typical usage ratio

• 0.2% to 3% in ready-to-use paints, depending on the desired tinting strength; crayons and pastels incorporate higher percentages for full-color payoff.

Downstream process integration

• Blended with binder resins and fillers during initial premixing; in aqueous paints, dispersed under high shear before final homogenization and filling.

Final product types

• Children’s poster paints, artist-grade watercolors, school crayons, modeling clays, colored chalks

5. Paper Coloring and Security Paper Production

Pigment Blue 27 is demanded by technical paper manufacturers for adding permanent blue tint to security and archival-grade papers, supporting both visible security features and substrate differentiation. The pigment’s high insolubility and fastness properties support compatibility with both acid and neutral papermaking processes in secure print shops.

Industry compliance standards

• ISO 9706 (Paper for documents – permanence)
• EN 643 (European list of standard grades of paper and board for recycling)
• PD ISO/TR 19300 (Security printing anti-forgery guidelines)
• REACH Regulation (EC) No 1907/2006

Typical usage ratio

• 0.03% to 0.2% based on pulp mass; fine-tuned to achieve uniform blue across large reels while maintaining paper strength and writeability.

Downstream process integration

• Dosed at the wet end prior to sheet formation in the pulper or mixing chest, allowing uniform distribution before dewatering and calendaring.

Final product types

• Watermarked security paper, banknote substrates, cheques, archival paper, examination papers

6. Industrial Leather Finishing

Leather finishing chemical manufacturers select this pigment to impart deep blue and turquoise shades to full-grain, corrected-grain, and split leathers. Applications require high resistance to sweat, abrasion, and light, assured by the pigment’s compatibility with finishing lacquers and aqueous coating systems customized for automotive, footwear, and upholstery leathers.

Industry compliance standards

• EN ISO 11640 (Leather – color fastness to cycles of to-and-fro rubbing)
• EN ISO 17075-2 (Determination of chromium(VI) content)
• REACH Regulation for restricted substances in leather articles
• ISO 15700 (Leather — Test for migration of color to other materials)

Typical usage ratio

• 0.07% to 0.5% in finishing formulations; exact levels depend on the depth of shade and type of leather processed, with higher percentages used for deep blue finishes on split leather.

Downstream process integration

• Mixed with binders and additives during the topcoat or basecoat preparation, then applied using spray or roller coating after leather drying and buffing stages.

Final product types

• Automotive seat upholstery, blue fashion leathers, shoe uppers, luxury leather goods
