Hyperdispersant for
solvent based applications
Chemical Composition
Non-polarity hyper-dispersant. Polymer containing amine anchor group.
Chemo-physical Properties
Appearance: Slightly brownish paste
Active ingredient: 100%
Amine value(mgKOH/g): <5
Characteristics
Containing amine anchor group, for better adsorption to pigment surface.
Improving system fluidity, color strength and gloss.
Preventing pigment coagulation, improve storage stability.
Application scope
Ink: Used as dispersant for offset ink, low polarity gravure ink.
Paint: Used directly as dispersant in industrial paint such as alkyd resin system.
Plastic: Used as dispersant for lower polarity masterbatch and plasticizer pigment paste.
Pigment: Used as pigment modifier to modify pigment for offset ink, gravure ink and industrial paint purpose.
General application guidance
For organic pigments, use 4-12% on dry pigment basis.
For inorganic pigments, use 2-8%.
For carbon black, use 10-30%.
Application tips
For use directly in inks and paints,
Dissolve dispersant in grinding mixture and followed by adding pigments.
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, or dissolve the dispersant into rosin solution.
For Azo-pigment. Add the emulsion to the rosin solution before or after the coupling step, or to the paste before filtration.
For Phthalocyanine pigment. Base on P.B.15, P.B.15:3 cake, add 10% sulphonated phthalocyanine while stiring, heat the mixture to 60-70℃, add 10-15% dispersant,continuing stiring at same temp. For 2 hours, filtrate and bake to dry to obtain P.B.15:2, P.B.15:4.
Greatly improve pigment performance on fluidity, color strength and dispersion. Widely used in modifying pigment such as P.R.57:1, P.Y.12, P.Y.174, etc. .
