Hydroxyethyl methyl cellulose(HEMC)For Construction

Improves uniformity, makes plastering easier to apply, and increases resistance to downdraft.  Enhance fluidity and pumpability to improve work efficiency.

High  water retention,prolong the working time of mortar,improve working efficiency,and help mortar develop high mechanical strength during solidification.

Air infiltration is controlled, thus eliminating micro-cracks in the coating and forming the ideal smooth surface.

Make the dry mixing ingredients easy to mix, will not produce clumps, thus saving the working time, because the application is faster and more effective, can improve the construction and reduce the cost.

Product Details

Hydroxyethyl methyl cellulose ether soluble in water and some organic solvents.  Can be dissolved in cold water, its highest concentration is determined only by viscosity, solubility changes with viscosity, the lower the viscosity, the greater the solubility.  Because the aqueous solution has surface active function, can be used as colloid protectant, emulsifier and dispersant, the highly concentrated aqueous solution of the product has special viscoelastic properties compared with the aqueous solution of other polymers, and its addition has the ability to improve the shape of extruded ceramic products.

HEMC Main application

Hydroxyethyl methyl cellulose (HEMC) is a non-ionic cellulose mixed ether made from cotton and wood through alkalization, ethylene oxide and methyl chloride etherification. HEMC is widely used in water-based latex coatings, construction and building materials, printing ink, oil drilling and other fields. Its properties are similar to HPMC, but the presence of hydroxyethyl makes HEMC more soluble in water, the solution is more compatible with salt, and has a higher condensation temperature.

1. in the pharmaceutical field, hydrophilic gel framework materials and pharmaceutical excipients for the preparation of sustained-release preparations are widely used, including oral tablets, suspensions, local preparations, porogens and coating agents.

2. in the field of food processing, it is used for bonding, emulsification, film-forming, thickening, suspension aid, dispersion, water retaining agent, etc.

3. in the field of daily chemical industry, it is used as an additive for toothpaste, cosmetics, detergent, etc.

4. in the field of building materials, it is used as a gelling agent and water retaining agent for cement, gypsum and lime, and is an excellent admixture for powder building materials.
