Applications of Helio blue B in Industrial Manufacturing

Helio blue B, as a copper phthalocyanine-based pigment, supports multiple downstream industrial production sectors requiring high color strength, lightfastness, and stable dispersion in complex chemistries. The following scenarios provide concrete integration points within manufacturing operations.

1. Offset Printing Ink Production

Offset ink formulators select Helio blue B for its high tinctorial strength and solvent resistance, making it suitable for process color sets. The pigment disperses in vehicles during the initial dispersion phase, typically in bead mills under controlled temperature to ensure micronized particle size and achieve required gloss and rheology. Our plant supplies consistent batches compatible with resins and additives used in advanced four-color offset systems for books, magazines, and packaging applications.

Industry compliance standards

• ISO 2846-1:2017 (Color and transparency for offset inks)
• EuPIA Exclusion Policy for Printing Inks
• REACH Regulation (EC) No 1907/2006 compliance for pigments
• AP89(1) German BfR Printing Inks Regulation for food packaging

Typical usage ratio

• 10-20% of total pigment load, varying by color depth targets and press type
• Ratio adjusted for desired transparency and printing substrate (coated/uncoated stock)

Downstream process integration

• Pigment dispersion occurs during pre-mixing and milling before let-down
• Inks undergo fine filtration and quality control for viscosity, particle size, and color development
• Blend enters automated ink filling/packing systems

Final product types

• Sheet-fed offset inks
• Web offset coldset and heatset inks
• UV-curable offset inks for specialty packaging
• Low-migration inks for food contact applications

2. Waterborne Automotive Paints and Coatings

Automotive OEM and refinish coatings depend on stable blue chroma for original equipment and bodyshop repairs. Helio blue B disperses in water-based acrylic emulsions during let-down, achieving high hiding power and outdoor durability. The pigment undergoes high-shear dispersion with wetting agents to meet automotive weathering cycles and maintain gloss, without migrating or fading under UV exposure in multi-layer clearcoat assemblies.

Industry compliance standards

• ISO 16474-2:2013 (Weathering tests for paints and varnishes)
• GMW3059 (General Motors Approved Materials for Paint Systems)
• EU Directive 2004/42/EC Limitation of VOCs in vehicle refinishing products
• Global OEM restricted substances list (RSRL), heavy metal limits

Typical usage ratio

• 3-8% w/w of total pigment in ready-mix coating
• Ratio set during shade matching with high-performance black and white pigments

Downstream process integration

• Blend pigment into basecoat using high-shear mixer, followed by let-down with resin
• Apply to test panels for color consistency and weathering trials
• Finish with clearcoat or metallic flake overlays

Final product types

• OEM automotive waterborne basecoats
• Commercial vehicle and bus finishing systems
• Automotive repair and refinish paints
• Aftermarket vehicle touch-up kits

3. Plastics Masterbatch Concentrates

Plastics compounders utilize Helio blue B in polyolefin and engineering resin coloring. The pigment is loaded during masterbatch extrusion, where it withstands high processing temperatures without color shift or decomposition. Dispersions are optimized using carrier-specific wetting agents and dispersants, with masterbatch pellets controlling chromaticity, opacity, and migration resistance in high-performance films and molded goods.

Industry compliance standards

• RoHS Directive 2011/65/EU (Restriction of hazardous substances in plastics)
• EN 71-3 (Toy Safety Chemical Requirements)
• FDA 21 CFR Part 177 - Indirect food additives in plastics (when applicable)
• EU Regulation No 10/2011 - Plastics in contact with food (applicable grades)

Typical usage ratio

• 0.2-1.5% w/w in color masterbatches, subject to resin carrier and color strength requirements
• Adjusted for lightfastness and target opacity in downstream end-use

Downstream process integration

• Pigment is pre-dispersed in carrier resin, twin-screw extruder melts and blends
• Masterbatch granules incorporated in injection, blow molding, or film extrusion
• QC for delta-E color tolerance, migration, and thermal stability

Final product types

• PE and PP color masterbatches for films and rigid containers
• Plastic caps, closures, and bottles
• ABS/PS toys and technical parts
• PVC window profiles, automotive trim, and cables

4. Synthetic Fiber and Textile Dope Dyeing

Synthetic fiber producers use Helio blue B as a spin-dye in polyamide and polyester melt-spinning, introducing the pigment in chip or granule form before spinning. The pigment endures high shear and heat, providing deep, non-bleeding color directly in fiber, reducing water and energy usage compared to wet dyeing. Quality engineers monitor particle size to prevent spinneret blockage and test fastness specifications post-extrusion.

Industry compliance standards

• OEKO-TEX Standard 100 (Textile product safety)
• REACH Annex XVII (Restrictions on certain hazardous substances in textiles)
• GB/T 3920-2008 (Color fastness to rubbing)
• ISO 105-B02 (Color fastness to artificial light)

Typical usage ratio

• 0.1-0.8% pigment load by weight in polymer melt
• Ratio shifts by required shade and fiber denier; QA monitors batch uniformity

Downstream process integration

• Pigment mixed with polymer chips pre-spinning
• Feeds melt extruder and spinneret
• Post-processing includes drawing, texturizing, and winding

Final product types

• Solution-dyed PET and nylon textiles for sportswear
• High-lightfast automotive upholstery
• Outdoor geotextiles and technical fabrics
• Colored sewing yarn and monofilament

5. Industrial Water-Based Paints

Producers of architectural and industrial paints select Helio blue B for water-based dispersion systems. The pigment integrates into pigment grind bases via high-speed dissolvers, requiring optimized dispersant package selection for stability and brightness. Finished paints exhibit strong tinting strength, good scrub resistance, and minimal bleeding for demanding interior and exterior coatings.
