FR-40 is a cement friction-reducing additive which will reduce the apparent viscosity and improve the rheological properties of a cement slurry. FR-40 is a blend of co-polymer that can be used in slurries with salt concentrations greater than 18% (bwow)

FR-41 is a cement friction-reducing additive based on napthalene sulfonate copolymer, which will reduce the apparent viscosity and improve the rheological properties of a cement slurry. The improved rheological properties result in reduced frictional pressures during pumping and turbulent flow can be achieved at lower pumping rates. FR-41 works at 80°F to 380°F (27°C to 193°C) temperature range
FR-41L is a cement friction-reducing additive based on napthalene sulfonate copolymer dissolved in an aqueous carrier, which will reduce the apparent viscosity and improve the rheological properties of a cement slurry. The improved rheological properties result in reduced frictional pressures during pumping and turbulent flow can be achieved at lower pumping rates.
