AMPS Base Synthetic Retarder
Risol RT100S
Description
AMPS base retarder Risol RT100S is a kind of synthetic and harmless cement retarder specially designed for environmental sustainability. It is a highly biodegradable and dispersible retarder designed for high temperature design in environmentally sensitive areas. The retarder has good compatibility with H and G cement. It is compatible with other additives of oil well cement. The application of retarder Risol RT100S in cement slurry design can improve the predictability of thickening time. The thickening time of cement slurry with retarder Risol RT100S decreases proportionally with the increase of temperature.
