Description
Linear high-molecular polymer incorporating cationic, anionic and non-ionic groups. Grey-yellow powder, water-soluble to form viscous liquid.
Appearance
White to light-grey granules / powder.
Properties
With cationic groups on polymer backbone, FA367 provides good anti-caving and clay-hydration-inhibition capacity and improved thermal tolerance. Compatible with anionic, amphoteric and cationic drilling-fluid systems.

Application
Functions as coating inhibitor with good colloidal stability, temperature-resistance and salt-resistance. Applicable for fresh-water, seawater and saturated-salt-water drilling-fluid systems. Recommended dosage: 0.1%–0.3% for fresh-water mud; 0.5%–1.0% for salt-water mud.
Dosage Guidance
0.1%–0.3% for fresh-water mud; 0.5%–1.0% for salt-water mud.
