Characteristics

  • Contain multi-amine anchoring group for the pigment surfaces for better adsorption.
  • Reduce system viscosity and increase storage stability.
  • Increase color strength and gloss.

Application scope

Ink: used directly as dispersant in low polarity inks such as offset ink, gravure ink.
Paint: used directly as dispersant in industrial paint with alkyd resins.
Plastic: used as dispersant for plastic masterbatch and plasticizer paste.
Pigment: used to treat pigments to be used in such low polarity systems.

General application guidance

For organic pigments, use 4-12% on dry pigment basis.
Inorganic pigments use 2-8%.  For carbon black, use 10-30%.

Application tips

For use directly in inks and paints,
    • Dissolve dispersant in grindingmixture and followed by adding  For better results, use together with 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, or dissolve the dispersant into rosin solution.
    • For Azo-pigment. Add the emulsionto the rosin solution before or after the coupling step, or to the paste before  For yellow azo-pigment, use together with WinSperse 2020 for better results.
    • ForPhthqalocyanine  Base on P.B.15, P.B.15:3 cake, add 10% sulphonated phthalocyanine while stiring, heat the mixture to 60-70℃, add WinSperse 3030 10-15%,continuing stiring at same temp. For 2 hours, filtrate and bake to dry to obtain P.B.15:2, P.B.15:4.
    • ForPrussian blue cake:At 60- 70℃, add 5-7% WinSperse 3030 with
