WinSperse 5050

WinSperse 5050

Pigment modifier for aqueous and solvent applications

　Chemical Composition

　Application tips

　Dissolve 5050 in 10-20X hot　water, add to the coupling　solution before the coupling step.Use 3-5% on a dry pigment　basis.

　For P.B.15:3, use xylene to　dissolve. Use 3-5% on a dry　pigment basis.

　For making P.Y.12, add 3-4%　5050 into the coupling component　solution. Such modified pigment　is used in offset, aqueous inks for　a more vibrant color with higher　color strength and greenish hue.

　Characteristics

　Storage

　Used to modify P.B.15:3 for offset　ink. Such modified pigment has　a more vibrant color with higher　color strength and gloss.

　Used to modify benzidine yellow　pigments for offset and aqueous　inks. Such modified pigment has　a more vibrant color with higher　color strength and gloss.

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

　After partial use, re-seal the　container.

　Application Scope

　Mainly used to modify the yellow　azo-pigments for use in offset　inks. Used in smaller amount can　also be beneficial for aqueous　inks to increase color strength　and opacity. E.g. PY.12,PY.13,PY.14.

　Used in the non-base-boiling　production process of P.B.15:3　during the ball-milling step for　better use in offset inks.
