FA367 Zwitterionic Polymer Encapsulating Agent is a water-soluble polymer which is copolymerized with anionic, cationic and non-ionic vinyl monomers.
FA367 Zwitterionic Polymer Encapsulating Agent is a water-soluble polymer which is copolymerized with anionic, cationic and non-ionic vinyl monomers. FA367 inhibits cutting from dispersing and swelling improves the drilling fluids viscosity. FA367 inhibits the contamination caused by cutting and cutting powder, reduce the content of harmless submicron particles so as to improve ROP and protect reservoir. The typical concentrations of the product range from 0.7 - 3.5 ppb.
