CG212L Polymer Fluid Loss Additive Liquid — Anti-sedimentation type
  • Instructions
  • MSDS
  • Professional Standard

SUMMARY  

  1. Fluid loss additives are added to reduce uncontrolled water loss from the slurry into the porous formation.
  2. Specially designed for lightweight cement slurry system and normal density cement slurry with strong dispersity.
  3. Has thickening effect on cement slurry, enhances its suspension stability and prevents sedimentation.
  4. Fast early strength development of set cement.
  5. Used blow temperature of 180℃(356℉, BHCT).
  6. Applicable mixing water: from fresh water to salt-saturated water.
  7. Compatible well with other additives.
  8. Mixed with water when applied and water quality is not required.
  9. The following technical data and parameters are based on our standard type, CG212L. Customized products are available upon receipt of customers’ specific requirements.
