With the development of industry and the improvement of living standards, pigment is more and more applied to paint ink industry to give better apparent effect. Unlike fuel, pigments are usually insoluble in the medium used, and in the case of large lock brushes they exist as aggregates. In order to get good coloring power, covering power and chroma, the aggregate of pigment must be opened and kept stable.

If the pigment is not dispersed well, many defects may occur, such as: flocculation, loss of light, color deviation, floating color flower, Benard vortex, precipitation, etc. And that's where the dispersant comes in.

In modern coating production, dispersant mainly plays the following roles:

★ Improve grinding efficiency, shorten grinding time, reduce production cost.

★ Prevent coarse back and granulation

★ Improve luster and fresh reflection, improve leveling effect

★ Improve floating color hair flower

★ Improve coloring power, improve color performance

★ Reduce viscosity, improve the fluidity of the color paste system, increase the amount of pigment loading

★ Reduce flocculation, increase construction and usability

★ Improve system stability, including storage stability, anti - sinking performance, anti - solvent impact performance

★ Increase color distribution, increase color saturation

★ Increase transparency (most organic pigments) or cover power (most inorganic pigments)
