General introduction

CPAM is a copolymer of acrylamide , potassium acrylate and organic cation monomer, with its molecular weight about 3 million to 8 million. Compared with cationic polyacrylamide, it has the characteristics of lower cost, better water loss effect. Compared with polyacrylamide potassium, it possesses better flocculating and cuttings carrying capacity.

Characteristics

•  Effectively coat cuttings, inhibit hydrous disintegration, and keep rule hole.

•  Grid structure of polymer can improve cutting carrying ability, which can keep hole clean.

•  Increase viscosity and improve rheology behavior.

•  Good compatibility, especially with sulfonates of tannin and sulfonateds of lignite and sulfonates of phenol resin.

•  Simple application method on site; directly added or mixed with water.

Method of application

Routine dosage is in the range of 0.1 ~ 0.3 % ,which is up to the condition under well.

Notes

This product should be stored in a cool, ventilated place to avoid the sun and rain. Flush with lots of water if splashing it into eyes.

Package
