Generic Pigment Blue 15:3 - Vibrant Blue for Paint and Ink Applications
Pigment Blue 15:3 delivers exceptional color vibrancy and reliability for paints, inks, and industrial coatings. As a β-phase copper phthalocyanine pigment, it combines intense greenish-blue hues with outstanding resistance to environmental and chemical stressors, making it ideal for both decorative and functional formulations.
Key Performance Features
1. Superior Lightfastness
Tested under ISO 105-B02 standards, Pigment Blue 15:3 achieves Class 8 lightfastness in full-shade applications and Class 7–8 in tinted systems (1:50 TiO₂ reduction) when evaluated against the Blue Wool Scale. This performance ensures minimal color shift (<ΔE 1.5) after 1,000 hours of accelerated xenon-arc exposure, making it suitable for outdoor architectural coatings and automotive finishes.
2. Acid/Alkali Resistance
Demonstrates Grade 5 resistance (per ISO 105-A03 Gray Scale) in harsh chemical environments:
- Acid resistance: No visible color change after 24-hour immersion in 2% H₂SO₄ solution
- Alkali resistance: Maintains ΔE <0.8 following 48-hour exposure to 5% NaOH solution
This chemical inertness enables use in industrial cleaning product packaging and chemical tank coatings.
3. Water Resistance
When tested via ISO 105-E01 methodology, the pigment exhibits Grade 4–5 water fastness:
- Heating aqueous dispersion to 70°C for 30 minutes yields colorless filtrate
- No pigment migration observed in waterborne ink films (ASTM D4946)
Ensures color stability in marine coatings and exterior latex paints exposed to prolonged moisture.
4. Solvent Resistance
Achieves Grade 5 solvent stability (ASTM D2792):
- Ethanol extraction tests show <0.01% pigment leaching
- Zero bleeding in hydrocarbon-based flexographic inks
Guarantees color integrity in alcohol-based sanitizer packaging and solvent-borne industrial primers.
Technical Highlights
