Hyperdispersant for solvent based applications
Chemical Composition
Non-polar acidic polymer
Chemo-physical Properties
Appearance: Brownish paste
Active ingredient: 100%
Acid value(mgKOH/g): 35-40
Characteristics
Reduce viscosity and improve pigment dispersibility.
Increase color strength.
Application scope
Such treated pigments are used in plastics and masterbatch, especially in plastics with low polarity.
Used in plasticizer paste as a pigment dispersant.
General application guidance
For organic pigments, use 4-12% on dry pigment basis.
Inorganic pigments, use 2-8%.
Application tips
For use in plastics, melt the dispersant with heating before mix with resin, then add pigment.
For modifying pigments during synthesis.
First, make emulsion using 4 parts of the dispersant and 1 part non-ionic emulsifier 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
