HEMC is hydroxyethyl methyl cellulose ether which can be used in Construction applications.

Cellulose ether is a synthetic polymer made of natural cellulose as raw material by chemical modification. Cellulose ether is a derivative of natural cellulose, cellulose ether production and synthetic polymer is different, its most basic material is cellulose, natural polymer compounds. Due to the particularity of natural cellulose structure, cellulose itself has no ability to react with etherifying agent. But after the treatment of swelling agent, the strong hydrogen bonds between molecular chains and chains were destroyed, and the activity of hydroxyl group was released into alkali cellulose with reaction ability, and cellulose ether was obtained through the reaction of etherifying agent -- OH group into -- OR group.

1.Cellulose ether HEMC used in masonry mortar

It can enhance the adhesion with masonry surface, and enhance water retention, so that the strength of mortar can be improved. Improved lubricity and plasticity to improve construction performance, easier application to save time, and improved cost effectiveness.

2.Cellulose ether HEMC used in ceramic tile adhesive

The dry mixture is easy to mix without clumping, thus saving work time, improving workability and reducing costs due to faster and more efficient application. By prolonging the cooling time, the efficiency of brick pasting is improved. Provides excellent adhesion effect.

3.Cellulose ether HEMC used in plate joint filler

Excellent water retention, can prolong the cooling time and improve work efficiency. High lubricity makes application easier and smoother. And improve the anti - shrinkage and anti - cracking, effectively improve the surface quality. Provides a smooth and even texture, and makes the joint surface more cohesive.

4.Cellulose ether HEMC used in cement based plaster mortar

Improves uniformity, makes plastering easier to spread, and improves vertical flow resistance. Enhanced mobility and pumpability to improve work efficiency. It has high water retention, prolong the working time of the mortar, improve the working efficiency, and help the mortar to form a high mechanical strength during the solidification period. In addition, air infiltration can be controlled, thus eliminating micro-cracks in the coating, forming an ideal smooth surface.

5.Cellulose ether HEMC - self leveling floor material

Provides viscosity and can be used as an anti-precipitation aid. Increased fluidity and pumpability to improve the efficiency of floor coverings. Control water retention, thus greatly reducing cracking and shrinkage.

6.Cellulose ether HEMC used in water based coatings and paint remover

The storage life is extended by preventing solids from settling. It has excellent compatibility with other components and high biological stability. Rapid dissolution without clumping helps simplify the mixing process.

Produces favorable flow characteristics, including low sputtering and good leveling, which ensures excellent surface finish and prevents paint from flowing down. Enhance the viscosity of water-based paint remover and organic solvent paint remover, so that the paint remover will not flow out of the workpiece surface.

7.Cellulose ether HEMC used in forming concrete sheet

Enhance the machinability of extruded products, with high bonding strength and lubricity. Improve wet strength and adhesion of sheet after extrusion.

8.Cellulose ether HEMC used in gypsum Plaster and render plaster products

Improves uniformity, makes plastering easier to apply, improves vertical flow resistance and improves fluidity and pumpability. Thus improve work efficiency. It also has the advantage of high water retention, can prolong the working time of the mortar, and produces high mechanical strength during solidification. By controlling the uniformity of mortar consistency, high quality surface coating is formed.
