How Vanisperse CB works

Vanisperse® CB is amongst the most effective water-based dispersants available, especially for carbon black pigments.

It works by adsorbing onto particle surfaces and imparting steric and electrostatic stabilisation mechanisms. It is most effective in pH range 8 to 10.

Vanisperse CB functions both as grinding aid and dispersion stabiliser and improves fluidity at high carbon black concentrations. Vanisperse CB lowers both initial viscosity and gelling on standing, and reduces or eliminates free water. The viscosity of the final dispersion for various substrates varies with dispersant dosage. Reduced milling times and higher loading both serve to lower manufacturing costs.
