Dispersant is a surfactant with two opposite properties, lipophilicity and hydrophilicity, in the molecule. It can evenly disperse the solid and liquid particles of inorganic and organic pigments that are difficult to dissolve in liquids, and at the same time prevent the sedimentation and aggregation of particles, forming the agent required for stable suspension. The role of dispersant is to use wetting dispersants to reduce the time and energy required to complete the dispersion process, stabilize the dispersed pigment dispersion, modify the surface properties of pigment particles, and adjust the mobility of pigment particles.

Characteristics of water-based carbon black dispersant:

  1. Good and stable wetting and dispersibility for both organic and inorganic pigments, especially suitable for dispersing carbon black pigments;
  2. Provide color development and stability;
  3. Low-viscosity pigment dispersion system can be obtained at a higher pigment content.

Scope of application: environmentally friendly water-based color paste, water-based ink.

Application method: The dispersant should be dispersed in the water medium first, and then the pigment is added for high-speed grinding.
