Increased Productivity
Productivity describes the level or amount of paint or ink that
can be produced in one process. Increases in productivity (i.e. increases in the
volume of coating produced) can be achieved when the pigment concentration is increased
in the dispersion.
Incorporation of the appropriate hyperdispersant into the dispersion makes it possible,
through the viscosity reducing effect, to increase the pigment content in a millbase.
Productivity gains result from being able to disperse more pigment in a given time
and thereby produce more final product from a given weight of millbase.
Productivity is also improved by having a significantly faster dispersion rate,
with less machinery wear, lower energy consumption and, most important, lower labour
and fixed costs for every kilogram of final product produced.

on production capacity
The graphic above illustrates the gain of productivity related to the use of hyperdispersants
compared to a standard dispersant.
