What is water soluble carbon black?

Water-soluble pigment carbon black has good water solubility and is easy to dissolve in water. It can be used in systems where water is the solvent, and can reduce the black pigment of flying powder type during construction. It has the characteristics of high blackness, strong coloring, less addition, and stable quality. It can be directly dispersed in water and can remain stable for several months.

About 8% of the output of carbon black manufacturers is used for the coloring of coatings, inks, plastics and other products, which we call pigment carbon black. The importance of pigment carbon black is second only to rubber carbon black, which is characterized by a finer particle size than rubber carbon black, generally 9-30nm.

For pigment carbon black, the important performance "tinting strength" is stipulated as "conforming to the standard range jointly determined by both supply and demand", which shows the flexibility of pigment carbon black product standards.

Pigment product principle: the surface of ordinary carbon black is oily and cannot be well combined with water, which affects its blackness and color development. The product is modified to make the surface of carbon black have a strong affinity with water, which improves the carbon black. The color development, so as to achieve the effect of lower adding amount and higher blackness.

Later, with the advancement of science and technology, pigment carbon black evolved into water-soluble carbon black. The series of products are suitable for water-based coatings, colorants, papermaking, construction cement, cement products, thermal insulation boards, caulks and other products. Industry specific modified carbon black.
