Hydroxyethlmethyl Cellulose (HEMC)

1.Introduction

HEMC was designed for improved workability properties of all kinds of dry-mortars(tile cement, cement based render, thermal insulation mortar and gypsum plaster),HEMC is a new product family designed to give superior performance in hot climates .

   HEMC grades are able to bring the most important benefit of MHEC-chemistry to dry-mortars-thermo stability. Since it has an even higher flocculation temperature than ordinary used cellulose ether (always comparing types within similar viscosity range) it will show a benefit at elevated temperatures .i.e

2.It main properties compared to ordinary used cellulose ether chemistry:

  a. High temperature stability

  b. Slower cement setting, minor influence on gypsum plaster

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

  c. Sufficient water retention (viscosity dependent)

  d. Overall good workability

   MF grades can be used together with many organic and inorganic additives like surface active substance (air-entraining-agents) ,accelerators

Reactive air entraining agents and other water soluble polymers (starch ethers)

4. Storage 

  MF-series products are non-perishable products. It is recommended to use the products in rotating on a first out basis. 

The products should be stored under dry and clean conditions in its original packaging and away 

from heat. The packaging is selected in a way to avoid ingress of moisture , but the water content 

of the packed product will/may increase if not stored dry.
