WinSperse 3030

WinSperse 3030

Hyperdispersant for solvent based applications

　Chemical Composition

　General application guidance

　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%

　Amine value(mgKOH/g): 105-125

　Density(g/ml, 60℃):0.92-0.95

■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

　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 in low polarity offset and　gravure inks.

　Paint: Used in industrial paint with　alkyd resins.

　Pigment: Such treated pigments　are used in low polarity systems　such as offset ink, gravure ink　and industrial paint with alkyd　resins  for  much  improved　fluidity, dispersibility, without　compromising  color  strength.Especially suited for P.R.57:1,P.Y.12, P.Y.174 etc.

　Store in cool and dry places, good　for 2 year.

　After partial use, re-seal the　container.
