ACUMER™ 9300
ACUMER 9300 is the sodium salt of a polyacrylic acid selected for optimizing the factors affecting dispersancy in calcium carbonate, kaolin clay, titanium dioxide, and other mineral slurries.
Used in:
Mineral processing
Specifically for:
coarse grade
precipitated calcium carbonate (PCC)
low solids Kaolin clay (70%)
titanium dioxide
talc (typically in conjunction with a low foam surfactant for wetting purposes)
aluminum hydroxide
iron oxides
clay/barbotine for ceramics
ceramic tile

Advantages: Universal dispersant for stabilizing mineral slurries Allow lowering the viscosity at the time of initial formulation Maintain a low viscosity during storage Broad fomulating latitude Good cost performance Replacement for high cost phosphates such as sodium tripolyphosphate STPP and sodium hexametaphosphate (SHMP)
