    WinSperse 5140

    Pigment modifier for solvent based applications

     Chemical composition

     General application guidance

     Low polar polymer with pigment affinity groups

     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.


     Chemo-physical Properties

     Application tips

     Appearance: white to yellowish paste

     Active ingredient: 100%

     pH(1% aqueous solution): 3.0-4.5


     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.

     Characteristics

     Package

     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.

     Drum: 50kg/drum

     Application scope

     Storage

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

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

     After partial use, re-seal the container.
