Product details

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
As one of the major building insulation systems, ETICS/EFIS(External Thermal Insulation Composite System/Exterior Insulation Finishing System) is used to apply thermal insulating material and reinforcing mesh to the exterior of buildings. Hydroxyethyl Methyl Cellulose(HEMC) used in this application has following functions.
1) Adhesion strength: HEMC can provide the greatest degree of high adhesion strength of mortar;
2) Performance: During using of distribution method, the mortar added with HEMC has the right consistency, non-sagging. Improve workability and pot life.
3) Water retention: Can easily wet the wall insulation, easy to paste and make other additional materials achieve the best effect;
4) Absorbent: Can minimize the air-entrance volume and decrease water absorbing of the mortar.
5) Delay drying out of the mortar surface.
