Higher Processing Efficiency
To achieve the full color potential of a pigment, the pigment particles must be
properly dispersed in the coating system. Achieving optimal dispersion
quality exposes the full surface area of the carbon black pigment and
ensures the maximum absorption of visible light and consequently the best black
Cabot high color strength carbon black pigments:
Selecting the proper type of Carbon Black for specific systems enables formulators
to reduce dispersion time. Dispersing Carbon Black pigments in water-borne systems
is especially difficult. That is why Cabot has developed a surface treatment
technology specifically for water-borne systems. Ionic surface groups
on the pigment enable a mechanism called electrostatic stabilization to occur, causing
the pigment particles to automatically separate in water-borne systems. Grinding
times are shortened, dispersion costs are minimized, and formulators can reduce
dispersion time by more than 85% compared to the competitor benchmark.
Achieving good color performance requires not only proper pigment dispersion but
also maintaining dispersion quality until the coating is applied. Proper treatment
of the pigment surface prevents re-agglomeration of the pigment particles, enabling
long shelf lives for millbases, final formulations and ensuring
consistent final film properties.
In deep black coatings, dispersing aids are essential to ensure that small particle
size pigments are well dispersed throughout the coating system. By choosing the
appropriate pigment, formulators can minimize the amount of dispersing aid required.
In water-borne systems, Cabot's EMPEROR® products can reduce dispersing
aid loadings by more than 50%.
Actual results will vary based on specific dispersing aid used
The reduction of environmental impact is a major driver for coating
technology. With this aim, water-based coating technology can enable low or
no VOC coatings solutions. As formulators use water-borne technology
to replace solvent-borne formulations, they seek to match or exceed their current
performance levels. Cabot's EMPEROR® product family is designed
specifically for water-based systems and provides formulators
with high performance solutions for water-based systems. These
products deliver high color performance and also
high processing efficiency.
