Hyperdispersant for
solvent based applications
Chemical Composition
Non-polar polymer with basic amines
Chemo-physical Properties
Appearance: Brownish paste
Active ingredient: 100%
Amine value(mgKOH/g): 105-125 Density(g/ml, 60℃):0.92-0.95
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 in low polarity offset and gravure inks.
Paint: Used in industrial paint with alkyd resins.
Pigment: Such treated pigments are used in low polarity systems such as offset ink,
gravure ink and industrial paint with alkyd resins for much improved fluidity,
dispersibility, without compromising color strength. Especially suited for P.R.57:1, P.Y.12, P.Y.174 etc.
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,
Dissolvedispersant 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 emulsionto the rosin solution before or after the coupling step, or to the paste before filtration.
ForPhthalocyanine 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.
ForPrussian blue cake：At 60- 70℃, add 5-7% WinSperse 3030 with stiring.
