Polyvinyl Alcohol (PVA) Type

G307A Early Strength and Anti-channeling Fluid Loss Control Additive is a water-soluble polymer. In cement slurry, its molecular chain bundles aggregate, thereby reducing the permeability of the filter cake.

G307 reduces fluid loss in cement slurry by forming a dense polymer film and increasing the viscosity of the aqueous phase.

G306 reduces fluid loss by forming a dense polymer film and increasing the viscosity of the aqueous phase.
