Cobalt blue dye homogenization nailed it!
Particle size reduced by 98% straight to nano-grade
Goal: Cobalt blue dye D50<1μm, evenly dispersed with zero agglomeration.
Simple & no complex pretreatment:
1. Mix cobalt blue powder with pure water to make 20% solid content slurry
2. Homogenize directly at 1400 bar for 5 cycles
3. Sample & test particle size
Direct high-pressure homogenization works perfectly—no agglomeration, no delamination, particle size fully qualified.
Practical formula for high-end coloration needs.
