CF40P is powdered cement dispersant which can be dry blended with the cement or dispersed in water to provide uniform distribution throughout the cement slurry. The normal range of use for CF40P is 0.5 to 1.5 % BWOC.
CF40P can be used from low to high density slurries and with fresh water to saturated salt water up to 3500F, whereas regular dispersants only work up to about 2000F. CF40P will also complement the performance of most fluid loss additives.
CF40L is the liquid form of CF40P (which is a powdered product for dry blending with cement) however; both products perform the same function.
