SC440L MT RETARDER LIQUID
Product Description
1.Retarder helps extend the thickeningƟ me of cement slurry in order to keep it pumpable, which ensures sufficient pumping time for a safe cementing project.
2.Applicable for low-to-moderate temperature system, used below 90℃ (194℉, BHCT).
3.Mixed with water when applied, and water quality is not required.
4.When curing temperature is lower than bottom hole circulating temperature, strength of set cement at top may be affected.
5.The dosage of SC440L increases significantly when applied above temperature of 95℃, strength of set cement at top may be affected.
