    Ø For carbon black, use 10-30%.

    Application tips

    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
