Use
Dispersogen 2774 is used as a dispersing agent for
aqueous pigment preparations and printing inks.
Dispersogen 2774 is especially suitable for carbon
black and for organic pigments. The advantages of Dis-
persogen 2774 are
-high pigment concentration
-low viscosity of the preparation
-high stability of the preparation in a wide temperature range
-low foaming.
General recommendation of dosage for pigment preparations: 10 - 40 % on the organic pigments.
