Pigment modifier for

solvent based applications

Chemical composition

Low polar polymer with pigment affinity groups

Chemo-physical Properties

Appearance: white to yellowish paste

Active ingredient: 100%

pH(1% aqueous solution): 3.0-4.5

Characteristics

Used to modifying high performance azo-pigments such as P.Y.17, P.Y.81, P.Y.83, P.Y.180 to be used in plastics for higher color strength and dispersibility.

Application scope

Mainly used to modifying high performance yellow azo-pigment for plastic applications.

General application guidance

Use 5-10% on dry pigment basis.

Dissolve in 20X water before adding to the acid at the acid precipitation step, or to the coupling component solution.

Application tips

For making P.Y.83, mix 8%

WinSperse 5140 and 3% xylene and then added to the acetic acid solution during reverse acid precipitation step. This process produced smaller particles and solved the specific problem with PY.83. Adjust the pH=7.5-8.0 before filtration. Such obtained pigment has great gloss and dispersibility.
