Key benefits of using our Dyestuff Dispersants:

Milling Economy

Grinding efficiency is the ability to reduce the milling time required to achieve a desired particle size during milling.

Grinding particles to colloidal size increases the surface energy considerably. When a dispersant is adsorbed onto the dye particle, the surface energy is decreased, thus stabilizing the system. Fast adsorption of the dispersant and good repulsion between the particles improves grinding efficiency and stability of the dispersion.

We offer several lignin-based dispersants, which provide formulation economy by enabling milling at higher solids and spray drying at higher temperatures.
