Pigment Green TDD-73 - Stable Green Pigment for Paints and Inks
Pigment Green TDD-73 is a chromium-based inorganic pigment engineered to deliver exceptional color stability, chemical resistance, and environmental durability in demanding coating and ink applications. With its unique crystalline structure and surface optimization, this pigment achieves a deep, natural green hue (CIE Lab*: L* 38±2, a* -25±1, b* 15±1) while meeting stringent performance requirements for industrial, architectural, and specialty markets.
Key Performance Attributes
Superior Color Consistency
Featuring a controlled particle size distribution (D50: 0.8–1.5 μm via laser diffraction), Pigment Green TDD-73 provides 92–95% opacity at 25 μm dry film thickness, outperforming conventional chromium oxides by 15–20% in hiding power. Its narrow reflectance curve minimizes metamerism, ensuring consistent color matching across batches (ΔE ≤1.0 under D65 illumination). The pigment’s high tinting strength enables dosage reduction to 8–12% in full-shade systems while maintaining ISO 787-24 chromaticity standards.
Enhanced Durability Profile
- Weathering Resistance: Retains ΔE <2.5 after 3,000 hours of QUV-A exposure (ASTM G154)
- Thermal Stability: Withstands temperatures up to 400°C (DIN 53775) without discoloration
- Chemical Inertness: Resistant to acids (pH 2), alkalis (pH 12), and industrial solvents (ASTM D1308)
- UV Blocking: Absorbs 98% of UV-B radiation (280–320 nm) to protect substrates from degradation
Eco-Friendly Formulation
Manufactured through a closed-loop process, Pigment Green TDD-73 contains <50 ppm hexavalent chromium (tested per RoHS 3 Directive) and complies with EU REACH, TSCA, and China GB standards. Its low soluble ion content (<0.1% Cl⁻/SO₄²⁻) prevents corrosion in metal-containing coatings, while the absence of APEO and SVHC substances ensures compatibility with global sustainability initiatives.
Application Versatility
Industrial Coatings
- Heavy-duty epoxy systems for chemical tank linings (1,500+ hours salt spray resistance, ASTM B117)
- Powder coatings for architectural aluminum with AAMA 2605 compliance
