Product features
This product is a polyacrylamide copolymer, which can well maintain the stability of drilling fluid properties, and can effectively inhibit shale hydration expansion and keep drilling cuttings not dispersed, easy to remove. This series of polymers has a good coating effect on rock debris in fresh and salt water as well as in brine, with Temperature resistance above 150℃.

Method of application
The dosage is adjusted according to the site conditions to obtain the desired dispersion effect. The dosage is generally 0.1 to 0.4% in clear water and 0.4 to 1% in brine. It is recommended to prepare 1-2% polymer Aqueous solution and then add it to drilling fluid as required.
Store the product in dry and cool place, avoid insolation. Shelf life is two years.
