Summary
OBC-D11S is an aldehyde and ketone condensate dispersant, which can significantly reduce the consistency of cement slurry, increase fluidity, and improve the fluidity of cement slurry, thereby helping to improve cementing quality, reduce construction pump pressure, and accelerate cementing speed.
OBC-D11S has good versatility, can be used in a variety of cement slurry systems, and has good compatibility with other additives.
