WinSperse 3070

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. .
