Oil Well Cement Retarder

Oil Well Cement Retarder
Compatible with API cement class
Suitable for water-mixed
KWH-201L has a certain effect on strength of the set cement slurry when the cure temperature is lower than the bottom hole cycle temperature.
When the bottom hole cycle temperature is higher than 100 degrees Celsius, the amount of KWH-201L will be significantly increased.

KWH-201L includes standard type KWH_201L and anti-freezing type KWH-201L _A.

KWH-201L, having less effect on other properties of cement slurry, is only suitable for water-mixed and hasn’t any special requirements for water quality and compatible with all API class cement, with all other additives and all types of water.
