fluid loss additive filtrate reducer cementing additive
l Provide Fluid loss control in low, normal or high density cement slurries.
l Use at temperature blow 180℃(356℉, BHCT).
l Use in freshwater, or salt water, salt-tolerant up to saturation.
l The cement slurry system is stable with little free fluid.
l Good fluidity, will not lead to over-disperse or thickened and no need to add additional dispersant.
l Compatible well with other additives.
l Suitable for all API classes of cement.
l Mix with water, and no water quality required.
