Phthalo Blues Typically Fully Mixed in 45 Minutes

Maximum color strength and superior dispersion with Kady International rotor-stator mills

Phthalo Blue is one of the most widely used organic pigments in the coatings, ink, and plastics industries. Known for its intense tinting strength and excellent lightfastness, it is also notoriously difficult to disperse due to its strong tendency to form agglomerates.

Traditional mixers often require 2 to 6 hours to fully develop Phthalo Blue. With a Kady high-speed rotor-stator mill, the same pigment typically reaches full color development in just **45 minutes**.

Result: Faster production cycles, lower energy consumption, reduced pigment loading, and consistently higher color strength.


Why Phthalo Blue Is Challenging

  • Very fine primary particle size with strong cohesive forces
  • High surface area leading to rapid agglomeration
  • Requires intense shear to separate pigment particles
  • Easy to over-disperse or damage if using the wrong equipment

How Kady Mills Achieve 45-Minute Dispersion

Kady International’s rotor-stator technology generates extremely high shear, impact, and cavitation forces. The mill’s unique design creates a powerful vortex that pulls material through the rotor-stator gap at tip speeds up to 9,000 feet per minute.

Key Benefits for Phthalo Blue:

  • Full color development in 45 minutes — often reaching 95–100% of maximum tint strength
  • Uniform particle distribution — excellent gloss and transparency in inks and coatings
  • Reduced pigment usage — many customers report 10–20% less Phthalo Blue needed
  • One-step processing — no need for multiple passes through media mills
  • Energy efficient — shorter batch times mean lower total power consumption

Real-World Results

Manufacturers using Kady mills for Phthalo Blue dispersions consistently report:

  • Significant reduction in batch cycle time
  • Improved batch-to-batch consistency
  • Lower reject rates due to poor color development
  • Easier scale-up from lab to production
