    WinSperse 3163

    Mid-polarity hyperdispersant

     Chemical Composition

     General application guidance

     High molecular weight polyurethane with mid-polarity


     Chemo-physical Properties

     Application tips

     Appearance: yellowish viscous liquid 
     Active ingredient: 45%
     Solvent: xylene/butyl acetate/PMA
     Amine value(mgKOH/g): 10-15
     Density(g/ml, 20℃): 0.97-0.99

     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 yellow azo-pigment, use together with

    WinSperse 2020 for better results.

    ■ 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.

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



     Designed to reduce grinding time and viscosity while increasing pigment load with good ability to prevent re-coagulation.
     Increase color strength and gloss.
     No precipitation at low temperature.
     Especially suited for carbon black dispersion.

     Drum: 18kg/drum

     Application scope


     Paint:auto paint, repair paint, and industrial paint.
     Inks: Used to disperse pigments to make Keton-ester or aromatic solvent gravure inks and inkjet printing inks.

     Store in cool and dry places, good for 2 year.

     After partial use, re-seal the container.
