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%

Amine value(mgKOH/g): 180-200

Density(g/ml,40℃): 0.87-0.89

Characteristics:

Especially well suited to modify pigment used in nitrocellulose systems for better viscosity and storage stability with higher color strength and gloss.

Application scope:

Organic pigment

General application guidance:

Use 3-8% on dry pigment basis.

Add 4 part of Winsperse 5170 and 2 part of acetic acid to 20X water to dissolve before use.

Application tips:

For making P.Y.13, P.Y.14, P.Y.83, add 3-8% WinSperse 5170 to the coupling solution, when the reaction temperature heated up, add 5-10% WinSperse 2020. Such modified pigment is used in nitrocellulose systems to improve color strength, gloss, viscosity and storage stability.

For P.B.15:3 cake, add 6-10% sulphonated phthalocyanine while stiring, heat the mixture to 60-70℃, add WinSperse 5170 10-15%, continuing stiring for 2 hours, filtrate and bake to dry to obtain P.B.15:4 for use in solvent based ink especially in nitrocellulose systems.

Package:

Drum: 17kg/drum
