Fluid Loss Control Additive for Oil Well Cement
Product Description :
G35S belongs to pure polymerization and water-soluble agent, reducing the slurry cake permeability by the aggregation of water-soluble high polymer molecular chain. At the same time, G35S introduces various functional groups into the polymer to improve the suspension properties of the cement slurry.
