Summary
This product is a kind of aqueous dispersion tubing-casing corrosion inhibitors mainly formed by macromolecule imidazoline. It is a very strong polar molecule with hydrophilic and lipophilic groupings each end. Lipophilic groupings can prevent the H2S, CO2 and HCL from corrosion to the metal effetely. The hydrophilic groupings formed a compact protective membrane on the surface of the metal to protect the metal from corrosion for a long time.
