FAQ About RT2390 Dispersant Agent
- Better dispersion efficiency;
- Relatively controllable viscosity influence;
- Better storage stability compared to small molecules;
- More cost-effective than high-molecular-weight dispersants.
It is mainly used for dispersing inorganic pigment fillers such as titanium dioxide, calcium carbonate, and talc, as well as medium pigment content water-based industrial coatings.
The addition amount needs to be adjusted according to the specific surface area of the pigment. At the same time, pay attention to the influence of the pH of the system and the content of electrolytes on the dispersion effect.
