Application

This additive is intended for use in the casing of oil, gas condensate, and gas wells for efficiently reducing the fluid loss in cement grouts and can be applied at temperatures from 15 to 200°Ñ, depending on the grade.

 

Processing

Polycem PF is added to the dry cement mixture and can be added, as required, to the tempering water of grouting mortar. The consumption of Polycem PF is determined by selecting, first of all, the mortar cement mixture composition. The tentative dosage ranges from 0.3 to 0.8% to dry cement weight for efficiently reducing the fluid loss indicator.

 

Packaging

The Polycem PF additive for reducing the water and gas permeability of cement stone is packaged in 25-kg polypropylene bags with a polyethylene liner.
