FC-R20L Polymer high-temperature retarder
Retarder helps extend the thickening time of cement slurry in order to keep it pumpable, which, therefore, ensures sufficient pumping time for a safe cementing project.
• FC-R20L is a type of organic phosphonic acid medium-low temperature retarder.
• FC-R20L can effectively extend the thickening time of cement slurry, with strong regularity, and has no impact on other properties of cement slurry.
• FC-R20L is applicable to slurry preparation of fresh water, salt water and sea water.

Concrete retarders are the mixture that slows down the chemical process of hydration so that the concrete remains plastic and workable for a long time, retarders are used to overcome the accelerating effect of high temperatures on establishing the properties of concrete in hot climates. Retarder can effectively prolong the thickening time of cement slurry so as to ensure a successful cementing operation. Foring chemicals has FC-R20L, FC-R30S and FC-R31S series to be used in different applications.
