WinSperse 3100

WinSperse 3100

Hyperdispersant for solvent based applications

　Chemical Composition

　General application guidance

Low-polarity  polymer  with  basic　amines

　For organic pigments, use 4-12%on dry pigment basis.

　Inorganic pigments use 2-8%.

　For carbon black, use 10-30%.

　Chemo-physical Properties

　Application tips

　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

　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 3030with stiring.

　Characteristics

　Package

　Contain multi-amine anchoring　group for the pigment surfaces for　better adsorption.

　Reduce system viscosity and　increase storage stability.

　Increase color strength and gloss.

　Drum: 18kg/drum

　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.
