    WinSperse 5170

    Pigment modifier for solvent based applications

     Chemical composition

     General application guidance

     Mid-to-low polar low molecular weight polymer with pigment affinity groups

     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.

     Chemo-physical Properties

     Application tips

     Appearance: yellowish solid

     Active ingredient: 100%

     Amine value(mgKOH/g): 180-200

     Density(g/ml,40℃): 0.87-0.89

     For  making  P.Y.13,  P.Y.14,P.Y.83, add 3-8% WinSperse5170 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.

     Characteristics

     Package

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

     Drum: 17kg/drum

     Application scope

     Storage

     Organic pigment

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

     After partial use, re-seal thecontainer.
