1. Gerneral Introduction

Hydroxyethyl Methyl Cellulose (HEMC) is made by high purity fine cotton through series of chemical processing under alkaline conditions. It do not contain any organs of animals, fat or bioactive constituents.

Hydroxyethyl Methyl Cellulose (HEMC) is a tasteless and odorless white or light yellowish powder, which appears to be a transparent viscous solution when dissolved in cold water. As Hydroxyethyl Methyl Cellulose is made by introduction of epoxy ethane substituent on the basis of Methyl Cellulose, it has higher gel temperature and better resistant to saline compared with unmodified polymer. 


2.Commodity Information

Name: Hydroxyethyl Methyl Cellulose (HEMC)

Other name:  2-Hydroxyethyl methyl cellulose; Cellulose methyl hydroxyethyl ether; Methyl hydroxyethyl cellulose (MHEC); Cellulose,2-hydroxyethylmethylether; 

CAS No.: 9032-42-2

HS CODE: 39123900


3.Properties

1)Solubility. Soluble in water (even cold water) and some organic solvents and solvent-water systems due to the hydrophobic groups in its molecule.

2) Surface activity. HEMC has a surfactant property in solution and can act as protective colloid and emulsifier.

3) Mildew resistance. Benefit from the good fungi and bacteria resistance, HEMC has excellent viscosity stability even for long time storage.

4) PH stability. The viscosity of the aqueous solution is almost not influenced by acid or alkali especially in the range of 3.0-11.0.

5) Low ash content. As the non-ionic product, it has very low ash content.

6) Water retention. HEMC can be used as efficent water retention for its hydrophily.

7) Other properties. Thickening agent, film former, adhesives, lubricants, suspending agent, shape retention, etc.


4. Function in ETICS/EFIS

Hydroxyethyl Methyl Cellulose(HEMC) used in pre-mixed dry mortaris an essential additive which can improve various properties such as sag resistance, workability, water retention, thickening effect once mixed with water. Follwing is the detailed function when used in different based plasters.

1) Reduce shrinkage or expansion of Cement Render during setting;

2) Improve water retention, workability and pumpability when used in cement based plasters.

3) Provides good workability while decuring stronger adhesion power between plaster and wall when used in Gypsum Hand Plaster;

4) Prevent material separation and improve adhesion and bonding  in gypsum adhesive field.

5) Provide strong tape adhesion power, easy workability and high water retention when HEMC used in Gypsum filler/ joint filler.
