　Chemical Composition

　General application guidance

　Chemo-physical Properties

　Application tips

 Appearance: yellowish viscous liquid 
　Active ingredient: 45%
　Solvent: xylene/butyl acetate/PMA
　Amine value(mgKOH/g): 10-15
　Density(g/ml, 20℃): 0.97-0.99

■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
