Lemon Yellow Pigment - Bright Yellow for Decorative Coatings and Plastics

Lemon Yellow Pigment embodies the pinnacle of color technology, delivering unmatched brightness, durability, and versatility for decorative and industrial applications. Engineered to meet the exacting standards of modern coatings and polymer systems, this organic-inorganic hybrid pigment combines intense chromaticity with exceptional resistance to environmental stressors. Whether enhancing architectural façades, creating eye-catching consumer packaging, or coloring durable automotive interiors, Lemon Yellow Pigment ensures reliable performance across diverse substrates while adhering to global safety and sustainability benchmarks.

‌Key Characteristics‌

‌1. Ultra-High Chromatic Intensity‌
Lemon Yellow Pigment achieves a luminous hue with CIELAB coordinates of ‌L = 92, a = -12, b* = 90**‌, offering 25% greater color saturation than conventional diarylide yellows. Its optimized particle size distribution (D50: 0.3–0.5 μm) ensures maximum light reflection, producing vibrant opaque finishes at low loading levels (1.2–2.0% in coatings, 0.8–1.5% in plastics).

‌2. Exceptional Lightfastness and Weather Resistance‌
Rated ‌Grade 7–8‌ on the Blue Wool Scale (ISO 105-B02), the pigment withstands ‌3,000+ hours‌ of accelerated QUV exposure (ASTM G154) with ΔE <1.5, making it ideal for exterior architectural coatings, outdoor furniture, and automotive trim.

‌3. Broad Chemical Compatibility‌
Resistant to acids (pH ≥3), alkalis (pH ≤11), and plasticizers (including DINP and DOTP), it maintains color integrity in PVC window profiles, polyolefin packaging films, and epoxy-based industrial coatings.

‌4. Thermal Stability for High-Temp Processing‌
Withstands polymer processing temperatures up to ‌280°C‌ (536°F), suitable for engineering plastics like PBT, nylon, and ABS. No color shift occurs below 230°C in injection molding or extrusion cycles.

‌5. Excellent Dispersion Properties‌
Pre-treated surface modification enables rapid incorporation (<10 minutes) in solvent-borne, water-based, and UV-curable systems. Achieves Hegman grind fineness of ‌7+‌ without milling aids, reducing production time by 20%.

‌6. Regulatory Compliance‌
APEO-free, heavy metal-free (passing EN 71-3), and compliant with REACH, RoHS, and FDA 21 CFR 175.300 for indirect food contact applications.

• ‌Plastic Masterbatches‌: 15–25% in polyolefin or engineering resin carriers
• ‌Printing Inks‌: 8–12% in flexographic/gravure systems for 100% color strength

‌Sustainability & Safety‌

• ‌Eco-Efficiency‌: 30% lower carbon footprint vs. cadmium-based alternatives
• ‌Biodegradability‌: 85% mineralized in 28 days (OECD 301B test protocol)
• ‌Non-Toxic Handling‌: SDS-certified; non-hazardous per OSHA 29 CFR 1910.1200

‌Technical Superiority‌

1. ‌Cost Efficiency‌: 18–22% reduced usage vs. isoindoline yellows at equal chromaticity
2. ‌Process Stability‌: Eliminates speckling in high-speed coil coating lines
3. ‌Batch Consistency‌: ΔE <0.4 between lots under D65/10° observation
4. ‌Global Approvals‌: Certified for China GB 24613-2020 and EU Ecolabel

‌Packaging & Logistics‌

• ‌Standard Units‌: 20 kg multi-wall paper bags with moisture-resistant lining
• ‌Bulk Solutions‌: 500 kg FIBCs with anti-static protection
• ‌Shelf Life‌: 36 months in sealed, climate-controlled storage

From sun-drenched architectural metalwork requiring decade-long fade resistance to food-grade plastic containers demanding FDA compliance, Lemon Yellow Pigment delivers uncompromised chromatic performance. Its fusion of aesthetic brilliance, environmental resilience, and formulation adaptability makes it the preferred choice for color engineers seeking to balance visual impact with technical rigor.
