Product Name: Hydroxyethyl Methyl Cellulose (HEMC)

Other Name: Methyl 2-hydroxyethyl cellulose (MHEC)

CAS No.: 9032-42-2

Gerneral Intruction:

Hydroxyethyl Methyl Cellulose is nonionic cellulose ether made by natural high polymer cellulose as raw material and series

of chemical processing. It's odorless, tasteless and nontoxic white powder, which can be dissolved in cold water to form

a transparent viscous solution. Possessing thickening, binding, dispersing, emulsifying, film coating, suspending, absorbing,

gelling,surface activity, water maintaining and protective colloid properties.

Hydroxyethyl Methyl Cellulose can be used in building materials, coating industry, synthetic resin, ceramic, pharmaceutical,

food, textile, agriculture, cosmetics and other industries.

Hydroxyethyl Methyl Cellulose is more stable in higher temperature environment.

Construction Industry Application Guide

1.Exterior Insulation and Finish Systems (EIFS)

Bond strength: HEMC/MHEC can provide the greatest degree of high adhesive bond strength of mortar;

Performance: During using of distribution method, the mortar added with HEMC/MHEC has the right consistency, nonsagging.

Making the mortar easy to work continuously in the applications;

Water retention: Can easily wet the wall insulation, easy to paste and make other additional materials achieve the best effect;

Absorbent: Can minimize the air-entrance volume and decrease water absorbing of the mortar.

2. Joint filler

Workability: HEMC/MHEC can provide the suitable viscosity, which has a good plasticity and easy to work;

Water retention: HEMC/MHEC can make the slurry fully hydrated, which extend the working time and avoid cracking;

Anti-slipping: HEMC/MHEC can make a strong adhesion on the surface for the slurry and not sag;

3. Self-leveling mortar

Prevent bleeding: HEMC/MHEC can play a very good role of suspension, to prevent the slurry sedimentation and bleeding;

Maintain liquidity and improve water retention: Low viscosity of HEMC will not affect the flow of slurry and easy to

work.

While possesses certain water retention, makes the good surface effect after self-leveling and avoid cracks;

4. Gypsum-based plaster

Water retention: HEMC/MHEC can retain moisture in the mortar, thus make gypsum completely solid. The higher of the viscosity,

the higher of the water-retention, vice versa;

Sag resistance: Allow the worker make a thick coating without causing ripple building;

Mortar yield: For fixed weight of dry mortar, the exist of HEMC/MHEC can provide more wet mortar;

5. Ceramic extrusion molding

HEMC/MHEC can provide good lubricity and plasicity, it can also provide the operational for ceramic molding;

Extremely low ash content can provide a very dense internal structure after calcination, while delicate rounded surface of

the product;
