Chemo-physical Properties | Application tips |
Appearance: yellowish viscous liquid | 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 |
