SUMMARY
- ST410S-T-AD can significantly reduce cement slurry consistency, improve liquidity and rheological behavior of cement slurry.
- ST410S-T-AD is applicable in a wide temperature range and is resistant to high temperature.
- ST410S-T-AD has salt resistance and still has good performance in 5%-10% brine cement slurry.
- ST410S-T-AD is suitable for both water and dry mixed, has no special requirement on the quality of mixing water and is soluble in cold water.
SPECIAL ATTENTIONS
- The performance of ST410S-T-AD will be obviously decreased when ST410S-T-AD is used in brine system, whose concentration is higher than that of the half saturated brine.
