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 inks.
  • 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 grinding mixture and followed by adding pigments. 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 emulsion to the rosin solution before or after the coupling step, or to the paste before filtration. For yellow azo-pigment, use together with WinSperse 2020 for better results.

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 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.

For Prussian blue cake:At 60-70℃, add 5-7% WinSperse 3030 with stiring.

 

Package

Drum: 25kg/drum

 

Storage

  • Store in cool and dry places, good for 2 year.
  • After partial use, re-seal the container.
