POLYMER RETARDER SC510 HT
Product Description
1.Retarder helps extend the thickening time of cement slurry in order to keep it pumpable, which, therefore, 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, and the top of the sealing section will not over-retarded.
4.Use below 150℃(302℉, BHCT).
5.Has good compatibility with polymer fluid loss additive, and little effect on high temperature fluid loss performance.
6.CH610 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.
