What is the reason for water floating on the surface of water-based color paste and how to solve it?

This shows that the compatibility of the color paste system is poor, the hydrophilicity of the color paste is not good enough, and the density of the liquid and the density of the powder are too different. You can try to add some thixotropic agent, or directly replace the dispersant and use a water-based resin-free color paste dispersant. High filling content, affinity for pigment groups, and no delamination.
