Polymer Fluid Loss Control Agent FS16L/S


AppearanceGrayLinen powder


FS16L/S fluid loss agent is a novel type of synthetic copolymer liquid. This product has good salt and temperature resistance capability, and effectively controls fluid loss within a large range of temperature and saturated salt water concentration. Thickening time is not sensitive to with salt concentration changes and thickness is stable. Prepared cement slurry has good stability.
FS-16L fluid loss agent can improve set cement microstructure, and enhances set cement flexibility. FS16L/S consists of solid FS16S and liquid FS16L. FS16L/S has certain dispersion
