Phthalocyanine Green TDD7P - Excellent Dispersion for Coating and Inks
Phthalocyanine Green TDD7P represents a breakthrough in pigment engineering, combining the unmatched chromatic intensity of copper phthalocyanine with advanced surface modification for superior dispersion in solvent-based and aqueous systems. Designed for high-efficiency colorant integration, this pigment delivers a brilliant bluish-green shade (CIE Lab*: L* 42±2, a* -35±1, b* 8±1) while addressing critical formulation challenges in modern coating and ink applications.
Key Performance Advantages
Unrivaled Dispersion Efficiency
Through proprietary micronization technology, TDD7P achieves a uniform primary particle size of 50–80 nm with aggregate control below 300 nm (DLS verified). This optimized morphology enables:
- 25% faster dispersion cycles compared to standard phthalocyanine greens
- Hegman grind fineness of 6–8 μm with standard polyurethane dispersants
- ≤5% viscosity increase at 15% pigment loading in high-solid coatings
Enhanced Color Performance
- 98% tint strength retention after 10,000 RPM dispersion (ISO 787-24)
- Metamerism index <0.8 under D65/A illuminants for critical color matching
- 0.5–1.0 ΔE shift in masstone after 500-hour QUV-B exposure
Technical Resilience
- Thermal stability to 280°C (30-minute exposure, DIN 53775)
- Chemical resistance to pH 2–12 solutions (ASTM D1308)
- 99.5% UV absorption between 300–400 nm wavelength
