Summary
ZOC-G87S-B has good versatility and can be applied to many kinds of cement slurry systems.
ZOC-G87S-B is suitable for a wide range of temperature, high temperature resistance to 180 degrees C, good fluidity and stability of cement slurry system, less free liquid and non retarding, rapid development and no special requirements for water quality.
Powdered synthetic polymer, doesn't increase thickening time, reduces Fluid Loss. Could be used at low and intermediate temperatures. Could be used as gas-block additive. Works in fresh water and salt water (18% BWOW) and temperatures below 121 degC. Optimal dosage - 0,3-1,0% BWOC.
