Medium-low temperature fluid loss agent XBA-203S
Introduction
XBA-203S is a compound power fluid loss agent.
XBA-203S’ applicable temperature is 0~90℃(BHCT).
XBA-203S is not retarded and benefited to cement strength development.
XBA-203S isn’t resistant to salt, not suitable for brine system.
XBA-203S has a certain effect in viscosity and some dispersant may be added in cement slurry.
XBA-203S only can be used through dry mixing.
