Risol FL900Sis 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. Risol FL900S is a medium to high temperature synthetic fluid loss additive.
It can be appliedin the seawater, and high salt content environment. Good salt tolerance makes it be workable for a variety of cement slurries.RIsol FL900S can be applied in regular weight and heavyweight cement slurries.The typical dose is 0.5-1.0%.
