Anionic Dispersant
Sodium polynaphthalene sulfonate anionic dispersant used to deflocculate and stabilize inorganic pigments and fillers in waterborne systems via electrostatic repulsion. It is highly effective for titanium dioxide, calcium carbonate, kaolin, and talc dispersions, reducing viscosity and improving pigment utilization efficiency. Compatible with latex and alkali-soluble resin systems.
