Ultramarine Blue Pigment 29 - Vivid Blue Color for Paint and Coatings
Product Overview
Ultramarine Blue, chemically classified as Sodium Aluminum Sulfosilicate (Na₈₋₁₀Al₆Si₆O₂₄S₂₋₄), stands as a cornerstone of inorganic pigments renowned for its vibrant blue hue with distinctive reddish undertones. Historically synthesized from lapis lazuli and now produced through advanced calcination processes, this pigment has been a staple in industrial and artistic applications since the 19th century. With unparalleled lightfastness, chemical stability, and eco-friendly attributes, ultramarine dominates sectors ranging from coatings and plastics to cosmetics and construction. Its unique ability to simultaneously color, whiten, and harmonize shades makes it indispensable for formulators seeking both aesthetic brilliance and functional performance.
Key Characteristics
1. Optical Excellence
- Red-undertone blue: Unique chromatic profile (CIE Lab*: L=35, a=15, b=-45) for depth and vibrancy.
- Whitening capability: Neutralizes yellow undertones in substrates, achieving ISO 2470-compliant brightness (>92%).
- Tinting strength: 0.1–2% loading achieves full opacity in most matrices.
2. Unrivaled Durability
- Lightfastness: Grade 8 on Blue Wool Scale (ISO 105-B02), resisting fading for 50+ years in outdoor exposure.
- Thermal stability: Withstands 350°C continuous heat, ideal for powder coatings and engineering plastics.
- Chemical resistance: pH-stable in 2–12 range, inert to acids (except strong mineral acids) and alkalis.
3. Material Compatibility
- Universal dispersion in:
- Polar/non-polar solvents (water, ethanol, xylene)
- Polymer systems (PVC, PE, PP, silicone)
- Aqueous/ solvent-based coatings (acrylic, epoxy, alkyd)
- Non-bleeding and non-migrating in elastomers and masterbatches.
4. Eco-Safe Composition
- Heavy metal-free: Compliant with EU REACH, FDA 21 CFR 73.2725, and Japan JHOSPA standards.
- Non-toxic: Approved for food-contact packaging and children’s toys (EN 71-3:2019).
- Low VOC: Zero solvent emissions in powder formulations.
Industrial Applications
I. Coloring Applications
Coatings & Paints
- Architectural coatings: Weather-resistant blues for exterior walls and roof tiles.
- Automotive finishes: High-gloss metallics with UV-stable undertones.
- Artistic paints: Preferred by fine artists for oil/acrylic mediums (Munsell 5B 4/10).
Polymers & Rubber
- Engineering plastics: Heat-stable coloration for automotive dashboards and appliance housings.
- Silicone products: Non-migrating pigment for medical devices and bakeware.
- Elastomers: Uniform dispersion in conveyor belts and footwear.
Printing & Packaging
- Security inks: Tamper-evident features for banknotes and certificates.
- Food-grade inks: USDA-compliant printing on snack wrappers and cartons.
II. Whitening & Brightening
Paper Manufacturing
- Eliminates yellowish cast in recycled paper (ISO brightness gain: 5–8 points).
- Alternative to optical brighteners in archival-grade stationery.
Detergents & Cosmetics
- Enhances whiteness perception in premium laundry powders.
- FDA-approved for lipsticks and eye shadows (CI 77007).
Building Materials
- Neutralizes efflorescence in white cement and gypsum boards.
- Anti-yellowing agent for PVC window profiles.
III. Tonal Harmonization
Neutral Tones Enhancement
- Gray modulation: Adds depth to automotive undercoat primers (5–15% blends).
- Black enrichment: Creates "midnight blue" effects in architectural glass.
Pastel Systems
- Softens harsh whites in infant products and hospital equipment.
- Achieves "ice blue" tones in acrylic bathtubs and sanitaryware.
