WinSperse 5150

WinSperse 5150

Pigment modifier for solvent based applications

　Chemical composition

　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.

　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

　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.
