[I] Hydroxyethy Methyl Cellulose (HEMC/MHEC)

Hydroxyethylmethyl cellulose (HEMC/MHEC) is used to improve the workability properties of all kinds of dry-motars.

 Hydroxyethylmethyl cellulose (HEMC/MHEC)

High temperature stabilitySlower cement  setting, minor influence on gypsum plaster

(Cost saving: dosage of retarders might be lowered, if used)

Sufficient water retention (viscosity dependent)Overall good workability

MF cellulose ether was designed for improved workability properties of all kinds of dry-mortars.MF grades can be used together with many organic and inorganic additives like surface active substances (air-entraining-agents), accelerators, reactive air entraining agents and other water soluble polymers (starch ethers).
