I.Product Introduction
Cement Retarder JXH210L can extend and adjust the thickening time of cement slurry.
when the cement slurry system using Cement Retarder JXH210L is used, when the curing temperature is lower than the circulation temperature, the development of compressive strength will be affected to a certain extent; when Cement Retarder JXH210L is applied above 100°C, its dosage will increase significantly.
