CH210L Moderate Temperature Retarder Liquid
  • Instructions
  • MSDS
  • Professional Standard

SUMMARY  

  1. Retarder helps extend the thickening time of cement slurry in order to keep it pumpable,which, therefore, ensures sufficient pumping time for a safe cementing project.

  2. Applicable for low-to-moderate temperature system, used below 90℃ (194℉, BHCT).
  3. Applicable mixing water: from fresh water to half-saturated salt water.
  4. Mixed with water when applied, and water quality is not required.
  5. When curing temperature is lower than bottom hole circulating temperature, strength of set cement at top may be affected.
  6. The dosage of CH210L increases significantly when applied above temperature of 95℃, strength of set cement at top may be affected.
