Oil Well Cement High Temperature Retarder

Oil Well Cement Retarder
Anti-High Temperature
Less effect on cement slurry
Suitable for water-mixed
Introduction
KWH-203L has a certain effect on strength of the set cement slurry when the curing temperature is lower than the bottom hole cycle temperature.

KWH-203L includes standard type KWH-203L and Anti-freezing type KWH-203L -A.
KWH-203L is suitable for water-mixed only and compatible with all API cement class, with all other additives and all types of water, and sea water and saline water. Moreover, KWH-203L has less effect on other properties of cement slurry.
