Chemi Tech Dispersant Enables 40%+ Solid Content in Water-Based Inks

Achieving >35% pigment content in resin-free water-based colorants often causes flocculation and viscosity instability. Chemi Tech's KMK-910 dispersant overcomes this through dual-function polymer design.

Technology: Graded Anchoring and Steric Hindrance

Multi-polar groups: -COOH/-NH₂ complexes form ion-hydrogen bonds with pigments, tripling adsorption energy;

Chain architecture: Alternating long-short polyether chains provide shear-thinning rheology.

Case: Flexographic Ink Production Upgrade in a Korean company

A packaging ink manufacturer using 38% carbon black slurry faced 120% viscosity rise after 7 days with KMK-910:

Stability: Viscosity variation <5%, zero settlement for 60 days;

Printability: Transfer rate increased 22%, dot reproduction >95%;

Efficiency: Dispersant dosage reduced 30%, grinding time cut by 40%.

Performance in Complex Systems

Phthalocyanine blue: Color strength boosted 18% in 15% glycol ether systems;

Gradient printing: No interlayer bleeding in overprinting;

High-temperature resilience: Stable at 80°C for high-speed drying lines.

Chemi Tech's molecular weight control (Mw=12,000±500) ensures KMK-910 activity across pH 4-12,
