WinSperse 5190

WinSperse 5190

Pigment water flush agent

　Chemical composition

　Application tips

　Low polar polymer with pigment　affinity groups

　For  yellow  azo-pigments,Dissolve 3-5% WinSperse5190

with 10-20X water, add it to　heated pigment paste. Or in

addition, in the process of　making  pigment,  use  3-5%　AASP or acetoacetyl benzoic　acid in the coupling step can　further improve thermal stability　and increase transparency and　color strength, and improve the　water flush efficiency.　

For  red  azo-pigments, add　WinSperse 5190 to the rosin

solution or to the paste.

　Chemo-physical Properties

　Package

　Appearance: white to yellowish paste

　Active ingredient: 100%

　pH(1% aqueous solution): 5.5-8.0

　Characteristics

　Storage

　High polar pigments and low polar　resin systems are not compatible　and normally have a more difficult　time to flush the water and achieve　phase conversion. This agent is　designed to facilitate this process for　less compatible pigment and resin　systems. It can bind to the polar　surfaces of the pigment particles to　decrease the polarity and increase　the water flushing efficiency.

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

　After partial use, re-seal the　container.

　Application scope

　Use 3-5% on dry pigment basis.
