Pigment modifier for
solvent based applications
Chemical composition
Mid-to-low polar low molecular weight polymer with pigment affinity groups
Chemo-physical Properties
Appearance: yellowish solid
Active ingredient: 100%
Acid value(mgKOH/g): 15-25
Amine value(mgKOH/g): 130-150
Characteristics
Such modified pigment is used in ink for better viscosity and storage stability with higher color strength and gloss.
Especially well suited to improve performance of pigment used in nitrocellulose systems.
Application scope
Mainly used to modifying yellow azo-pigment such as P.Y.13, P.Y.14 for use in mid-polar gravure ink.
General application guidance
Use 3-8% on dry pigment basis.
Add 1 part of Winsperse 5160 and 1 part of acetic acid to 20X water to Dissolve, heating maybe needed for complete desolution. Or, dissolve
Winsperse 5160 directly into the rosin solution before or after the coupling step.
Application tips
For better results in making yellow azo-pigments, use Winsperse 5160 together with WinSperse 2020.
