Advantages

  • Maximum deflocculation and shear strength reduction at low concentrations
  • 4 to 8 times more effective than lignosulfonates, depending on conditions
  • Soluble in systems of high salinity, high hardness and any pH
  • Scavenges oxygen and inhibits corrosion
  • High-temperature rheology control; proven effective in excess of 400 °F (204 °C)
  • Solution pH is approximately 8.5. No Caustic Addition is required to activate the product
  • Reduces the effects of cement contamination
