    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.

     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.
