Fluid Loss Additive AC167
Product Description
1.AC167 fluid loss additive is a synthetic polymer which is capable of effectively reducing water loss filtering from the slurry to porous formation during cementing process.
2.Disperse the slurry and help to control rheological behavior of cement slurry to prevent sedimentation and gelation problem.
3.No adverse influence to the thickening time of cement slurry in the working temperature range and shorten the transition time.
4.Assist in preventing anti-channeling.
5.Applicable in fresh water slurries and seawater slurries.
6.Used below temperature of 180℃(356℉, BHCT).
7.Compatible well with other additives.
8.AC167 series consists of L-type liquid, L-A type anti-freezing liquid, P-P type high purity powder, P-D type dry-mixed powder.
