PassAuthentication 
Compound zwitterionic polymer coating agent FA-367 for drilling fluids
purpose
This product can be directly applied to various water-based drilling fluid systems, and has good coating and inhibition.
Product features
This product is a white or yellowish powder. It is a water-soluble polymer. There are hydrophilic groups such as cation and anion in the polymer, which can inhibit the hydration of shale and have the effect of resistance to temperature, calcium and magnesium and salt resistance. It is a good drilling fluid inclusion agent.
