AC261 Fluid Loss Additive
Product Description
1.AC261 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.Prevent the reversal of thickening time and strength with temperature.
3.Mainly suitable for normal density cement slurry system.
4.Applicable in fresh water slurries.
5.Used below temperature of 180℃(356℉, BHCT).
6.Compatible well with other additives.
7.AC261 series consists of L-type liquid, L-A type anti-freezing liquid, P-P type high purity powder, P-D type dry-mixed powder and P-T type dual-use powder.
