retarder
C-R22L：
medium and low temperature retarder
C-R22L is an organic phosphate retarder, which can prolong the thickening time of cement slurry. Suitable for use in medium and low temperature environments.
Features:：
Low concentration sensitivity, Predictable thickening time, Suitable for mixing with fresh water and salt water, Especially effective for abnormal increase consistency of slurry while temperature rising
Applicable temperature BHCT < 100 ℃, organic phosphoric acid, used to solve the problem of cement heating and thickening in Xinjiang.
