Application
Starchy reagents PolyKR are easily soluble in fresh, sea, and saline water and allow regulating process fluid parameters at temperatures of up to 100°Ñ. The optimal process properties of drilling fluid are attained after its thermal treatment at 80–90 °C.
Processing
The recommended consumption of PolyKR reagents ranges from 5 to 30 kg per cubic meter of drilling fluid.
Packaging
PolyKR are packaged in 25-kg polypropylene bags with a polyethylene liner.Back
