Medium-low temperature Accelerator
Medium-low temperature Accelerator XBA-402S
Introduction
XBA-402S is an accelerator and benefited to cement strength development
XBA-402S can effectively shorten the thickening time of cement slurry.
XBA-402S can increase set cement’s early strength and shorten WOC(wait of cement) effectively.
XBA-402S could be used through wet or dry mixing.
