Applications & Uses

Coating Type
Usage Guide
  • Typical dosage is between 0.4% to 1.5% of active ingredient based on total pigment weight. However the optimum dosage for each formulation should be determined by measuring the dispersant demand of the pigment grind or slurry and adding an additional 50 to 100% dispersant as a safety margin. Too little dispersant will result in product instability and changes in viscosity. While too much can impair the water resistance properties of the paint film
