Hyperdispersant for

solvent based applications

Chemical Composition

Non-polar polymer with basic amines

Chemo-physical Properties

Appearance: Brownish paste

Active ingredient: 100%

Acid value(mgKOH/g): 12-20

Amine value(mgKOH/g): 18-26

Density(g/ml,30℃): 0.90-0.92

Characteristics

Especially suitable to improve dispersibilty of red azo-lake pigments in offset ink for a more vibrant color with much reduced viscosity and better storage stability.

Can also be used in improving color strength and viscosity for yellow azo-pigments such as P.Y.12, P.Y.174.

Application scope

Such treated pigments such as P.R.53:1, P.R.57:1, P.Y.12, P.Y.174 are used in offset inks and low polarity solvent inks.

General application guidance

Use 3-6% on dry pigment basis

Application tips

For use in yellow pigments. First, make emulsion using 4 parts of the dispersant and 1 part non-ionic emulsifier(or 4 parts of acetic acid) in warm water. Then add this emulsion to the rosin solution before or after the coupling step.

For use in red azo-pigments. Add to the rosin solution.
