SC810 UHT POLYMER RETARDER
Product Description
1.SC810 is a ultra-high temperature polymer retarder, which helps extend the thickening time of cement slurry in order to keep it pumpable, and ensures sufficient pumping time for a safe
cementing project.
2.Thickening time has a linear relation with the dosage and temperature. The Right-Angle thickening curve can be achieved.
3.Strength of set cement develops fast.
4.Use below 204.4℃ (400℉, BHCT).
5.Has good compatibility with polymer fluid loss additive, and little effect on high temperature fluid loss performance.
6.SC810 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.
