Hyperdispersant for

solvent based applications

Chemical Composition

Low-polarity polymer with basic amines

Chemo-physical Properties

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

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.
