Vericem R734

Setting retarder for wellbore cementing

Chemistry Type: Phosphonate Salt

Function(s): Cement Additives

Vericem R734 setting retarder for wellbore cementing can be used over a wide temperature range up to 140 °C (280 °F). It is used in combination with an accelerator (CaCl2) to tailor the setting time. It provides a linear dosage-retardation response between 65 - 105 °C (140 - 220 °F) and therefore ideal for the low to medium temperature range.

Key Advantages

  • Phosphonate-type long- and short-term cement setting retarder
  • Cement setting is activated by the addition of accelerators
  • Linear dosage-retardation relationship between 65 - 105 °C (140 - 220 °F)
  • Broad application temperature range up to 140 °C (280 °F)
  • Ideal for situations with delayed cementing jobs
