The great thing about liquid coloring is that it uses a liquid.
Therefore :
This liquid can be produced rapidly, in various quantities (from 500 g samples, for example, to several tonnes);
allows rapid mixing for color sampling ;
it allows dosages of the order of 10 –4 by mass, with great reliability (transparent shades);
it has the advantage of being compatible with most thermoplastic materials.
Thanks to these advantages, liquid coloring is highly popular in sectors requiring :
Highly flexible resources (various materials, multiple shades, variable production runs);
...
