Hyperdispersant for

solvent based applications

Chemical Composition

High molecular weight block copolymer with mid-polarity

Chemo-physical Properties

Appearance: yellowish viscous liquid

Active ingredient: 100%

Amine value(mgKOH/g): 32-40

Characteristics

Reduce grinding time and viscosity while increasing pigment load with good ability to prevent re-coagulation.

Improve color strength and gloss.  Especially suited for dispersing pigments in medium polar gravure inks.

Application scope

Ink: Medium polar gravure and UV inks.

Pigment: Modify the organic pigment surface to be used in medium polar gravure and UV inks and in auto and industrial paints.

General application guidance

Pigment                                      Carbon black

                                         （To dry pigment weight）

Organic                                            5-15%

Inorganic                                        2-6%

Carbon black                              10-50%

Application tips

For inks and paints, dissolve the hyperdispersant in the grinding mixture before adding pigments.

For better results, use together with WinSperse2010/2050.

For modifying pigment, first mix 1 part of the dispersant and 1 part acetic acid in warm water.

Then add this emulsion before or after the coupling step, or add to the paste before filtration step.

For better results, use acidic pigment derivative together with the dispersant.
