Effect of dispersants on coatings
Glossiness: If the gloss of the paint is to be high, the particles contained in it should not be larger than 5 microns, and the ink should not even be larger than 1 micron. Polymer dispersants can reduce the large particles formed in the paint and help the paint improve its gloss.

Carbon Black FAQs
What is carbon black?
Carbon black (also called carbon black) is a colloidal particle similar to a sphere formed by incomplete combustion or thermal cracking of hydrocarbon compounds (liquid or gaseous). It exists in the form of aggregates and appears as pure black powder or granular. The particle size, structure and surface activity of products vary greatly depending on raw materials, manufacturing methods and production processes. The main component of carbon black is carbon, and also contains trace amounts of hydrogen, oxygen, ash and moisture.

Recommended dosage of carbon black dispersant
The determination of the added amount usually requires consideration of the following factors:
Type and quality of carbon black: Different types and qualities of carbon black may require different amounts of Dongfugui dispersant. For example, the amounts of low-pigment carbon black, high-pigment carbon black, and conductive carbon black are completely different.

Carbon black dispersant used in water-based ink
Carbon black is a black powdery substance produced by incomplete combustion or thermal cracking of hydrocarbon compounds under strictly controlled process conditions. Its main component is elemental carbon and contains a small amount of oxygen, hydrogen and sulfur. Carbon black particles are approximately spherical in shape and have a particle size between 10 and 500 μm. They are one of the oldest industrial products.
