WinSperse 5070

WinSperse 5070

Pigment modifier for aqueous applications

　Chemical Composition

　General application guidance

　Use 3-5% on dry pigment basis.

　When used in aqueous solution,predissolve in 10-20X water.

　When used with organic solvents,mix first with organic solvents　followed by adding 10-20X water　with stiring to form emulsion and　then add to the coupling solution　before coupling.

　Chemo-physical Properties

　Application tips

　Appearance: Yellowish viscous liquid

　Active ingredient: 100%

　pH(1% aqueous solution): 8.5-10

　Density(g/ml, 20℃): 1.01-1.03

　For making P.Y.14, use 3% 5070 and　6% xylene to form emulsion first and　then add it to the coupling solution.Such modified pigment is used　in aqueous inks with higher color　strength, higher gloss and higher　hiding power.

　Characteristics

　Package

　Such  modified pigments in　aqueous applications have　higher color strength and gloss　with lower viscosity.

　WinSperse 5070 with organic　solvents as emulsifier used to　prepare pigments with better　hiding power.

　Non-APE, an  environmental　friendly replacement for OP-10　emulsifier.

　Application scope

　Storage

　Mainly used to modifying yellow　azo-pigments for use in aqueous　applications.

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

　After partial use, re-seal the　container.
