Hyperdispersant for

solvent based applications

Chemical Composition

Non-polar polymer with basic amines

Chemo-physical Properties

Appearance: Brownish paste to wax

Active ingredient: 100%

Acid value(mgKOH/g): 12-18

Amine value(mgKOH/g): 32-42

Characteristics

• Reduce viscosity, improve storage stability, increase color strength and gloss.

• Especially suitable for use to improve pigment dispersion in low polarity systems such as toluene ink, composite ink, offset printing ink.

Application scope

Ink: Used in low polarity offset and gravure inks.

Pigment: Such treated pigments used in low polarity offset and gravure inks.

General application guidance

For organic pigments, use 4-12% on dry pigment basis.

Inorganic pigments, use 2-8%.

Application tips

For use directly in inks, Dissolve dispersant in grinding mixture and followed by adding pigments. For better results, use together with synergists WinSperse2010/2050

For modifying pigments during synthesis. 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, or to the paste before filtration.

Package

Drum: 25kg/drum

Storage

• Store in cool and dry places, good for 10 year.

• After partial use, re-seal the container.
