KimaCell® MHEC MH400 methyl hydroxyethyl cellulose is prepared by introducing ethylene oxide substituents (MS0.3~0.4) into methyl cellulose (MC), and its salt resistance is better than that of unmodified polymers. The gelation temperature of MHEC is also higher than that of MC. MHEC is a common non-ionic water-soluble cellulose ether. It can improve the consistency and water retention of water-based products.

KimaCell® MHEC MH400 methyl hydroxyethyl cellulose is used as an additive for cement compositions. MHEC can be used as a multipurpose additive to prevent and/or control gas channeling, control fluid loss, minimize free flow, improve slurry stability and/or stabilize foam. Methyl hydroxyethyl cellulose (MHEC) can be used as an additive in cement slurry in well treatment to prevent or reduce the occurrence of gas channeling. In addition to acting as a gas control additive, methyl hydroxyethyl cellulose controls fluid loss, minimizes free fluid and stabilizes foam during cementing.
MHEC is easy to agglomerate when added to alkaline liquid. In order to avoid this phenomenon, the pre-solution should be prepared first, or the slurry should be prepared with weakly acidic water or organic solution, and it can also be added after dry mixing with other granular materials. The dissolution time after dispersion is greatly affected by the pH value of the water. Basic additives will speed up the dissolution process.
