Pigment modifier for

solvent based applications

Chemical composition

Polyamine polymer

Chemo-physical Properties

Appearance: white to yellowish paste or solid

Active ingredient: 100%

Characteristics

• This product has multiple anchoring points for the pigment surfaces; the long chains of this polymer provide special stabilization for the dispersed pigment particles.

• Such modified pigments have great solvent resistance and anti-coagulation, thus have improved color strength, gloss, viscosity and storage stability.

• Especially suitable for yellow pigments used in toluene ink.

Application scope

Mainly used to modify yellow azo-pigments such as: P.Y.12, P.Y.14，especially P.Y.12.

When used on P.Y.14, the pigment can be used in nitrocellulose, benzene-soluble poly amide systems with better gloss and viscosity.

General application guidance

Use 5-15% on dry pigment basis.

Add 2 part of Winsperse 5291 and 1 part of acetic acid to 20X hot water to dissolve. Can be used before or after the coupling solution. After the pigment paste heated to 90 degrees, adjust the pH=11.

Package

Drum: 160kg/drum

Storage

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

• After partial use, re-seal the container.
