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

‌Formulation Guidelines‌

‌Waterborne Systems‌

• Pre-blend with 4–6% polymeric dispersant (40% active)
• Mill using 0.5 mm zirconium oxide beads to Hegman 7
• Adjust pH to 8.0–8.5 with AMP-95 for optimal stability

‌Solvent-Based Applications‌

• Combine with 1–2% rheology modifier for sag control
