The evaluation of the quality of dispersants starts from the quality itself, and then determines based on the quality of the raw materials. For example, pigments have diversity and different surface characteristics, making the selection of dispersants more targeted. So we can evaluate them based on some of their phenomena, which provides a more subjective and objective comprehensive analysis of the problem.
We analyze that dispersants correspond to a certain pigment or formula, and there are several common phenomena:
1. The amount of additives used;
2. The ability of dispersants to reduce the viscosity of the system;
3. The impact on pigment dispersion time;
4. The influence of dispersants on the fineness of pigment dispersion;
5. Improvement and enhancement of pigment coloring power;
6. The impact on the storage stability of the system;
7. The impact on the gloss of the system.
