Wetting and dispersing agents are all surfactants, which can help to obtain a good coating dispersion system. The wetting agent plays a role in the wetting process of the pigment, reducing the interfacial tension between liquid and solid, which can improve the dispersion efficiency of the pigment and shorten the grinding time. Dispersants play a role in the pigment dispersion process, and can be adsorbed on the surface of pigment particles to form charge repulsion and steric hindrance effects, so that the dispersion is in a stable state. A new polymer surfactant with both wetting and dispersing effects.
