Chemical Reagent CF610S Dispersant SAF based<356F

 

 

 Summary

 

1. CF410S Dispersant can significantly reduce cement slurry consistency, improve liquidity and rheolog-

 

    ical behavior of cement slurry.

 

2. CF410S Dispersantis applicable in a wide temperature range and can be resistant to 356°F (180°C).

 

3. CF410S Dispersant has salt resistence and still has good performance in 5%-10% brine cement slurry. 

 

4. CF410S Dispersant is suitable for dry mixed as well as water mixed, soluble in cold water.

 

5. CF410S Dispersant is compatible with cement and other additives well.

 

 

Special Attentions

  

The performance of  CF410S Dispersant will be obviously decreased when  DISPERSANT CF410S  is used in brine system, whose concentration is higher than that of the half saturated brine.  

 

 

Applications

 

 

Temperature:Lower than 356°F (180°C) (BHCT)

 

Dosage: CF410S Dispersant generally 0.2-2.0% (BWOC), recommend amount 0.5% (BWOC).
