This product is a dispersing retarding type synthetic polymer fluid loss additive. It helps to reduce apparent viscosity and to improve the rheological properties of a cement slurry. It helps to handle slurries with reduced water/cement ration at temperatures up to 350F. It can be applied in the seawater, and high salt content environment up to 18%. Good salt tolerance makes it be workable for a variety of cement slurries. CF 130S can be applied in regular weight and heavyweight cement slurries. It is a mid to high temperature synthetic fluid loss additive. The typical dose is 0.5-1.2%.
