Low polarity hyperdispersant
Low-polarity polymer with basic amines
Appearance: Brownish paste
Active ingredient: 100%
Acid value(mgKOH/g): 4-10
Amine value(mgKOH/g): 35-45
Density(g/ml, 60℃): 0.89-0.91
Ø Contain multi-amine anchoring group for the pigment surfaces for
Ø Reduce system viscosity and increase storage stability.
Ø Increase color strength and gloss.
Ø Used directly as dispersant in low polarity inks such as offset
ink, gravure inks.
Ø Used directly as dispersant in industrial paint with alkyd resins.
Ø Used as dispersant for plastic masterbatch and plasticizer paste.
Ø Used to treat pigments to be used in such low polarity systems.
General application guidance
Ø For organic pigments, use 4-12% on dry pigment basis.
Ø Inorganic pigments, use 2-8%.
Ø For carbon black, use 10-30%.
Ø For use directly in inks and paints, Dissolve dispersant in
grinding mixture and followed by adding pigments.
Ø For modifying azo-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. Then add this emulsion to
the rosin solution before or after the coupling step, or to the
paste before filtration.
Ø For P.B.15, P.B.15:3 cake, add 10% sulphonated phthalocyanine while
stiring, heat the mixture to 60-70℃, add WinSperse 3100 10-15%,continuing stiring for 2 hours, filtrate and bake to dry to obtainP.B.15:2, P.B.15:4
Ø For Prussian blue cake:At 60-70℃, add 5-7% WinSperse 3030 with stiring
Ø For yellow azo-pigment, use together with synergist WinSperse 2020 for better results.
Ø Such treated pigments are used in offset ink for much improved
fluidity without compromising color strength. Especially suited for P.R.57:1, P.Y.12, P.Y.174 etc.
Ø Store in cool and dry places, good for 2 year.
Ø After partial use, re-seal the container.
