EHEC and MEHEC cellulose ethers
Bermocoll® EHEC (ethyl hydroxyethyl cellulose) and MEHEC (methyl ethyl hydroxyethyl cellulose) are non-ionic cellulose ethers, manufactured by a unique, solvent-free process, ensuring you a low carbon footprint and cellulose with carefully calculated performance characteristics.
We are the only producer in the world of EHEC and MEHEC. These are manufactured using cellulose from wood or cotton linters via alkalization, ethoxylation and reaction with ethyl- and methyl-chloride.
EHEC and MEHEC can also be reacted with longer chain hydrophobes, producing hydrophobically modified cellulose, HM-(M)EHEC, used as associative thickeners.
Our Bermocoll® products are used as rheology modifiers in a variety of industrial applications to create desired performance enhancements for both drymix mortars and paints.
Various applications of cellulose ethers in building and ...
Cellulose ether is an important polymer material widely used in the building and construction fields. It is a type of polymer compound obtained by chemical modification of natural cellulose. It has good water solubility, thickening, water retention and film-forming properties.
1. Thickener
In building materials, cellulose ethers are often used as thickeners. It can effectively increase the viscosity of materials and improve the working performance of materials. For example, adding cellulose ether to cement mortar and plaster can increase its consistency and make construction more convenient. At the same time, the thickening effect of cellulose ether can also prevent materials from sagging during construction and improve construction quality.
2. Water retaining agent
Cellulose ether has good water retention properties and can significantly reduce water loss. In cement-based materials, adding cellulose ether can reduce the water loss rate of cement and prolong its setting time, thereby improving the strength and durability of the material. In tile adhesives, the water-retaining effect of cellulose ether can ensure that the tiles do not fall off during the bonding process and improve the bonding strength.
3. Lubricant
Cellulose ethers can also be used as lubricants. Adding cellulose ether to concrete can improve the fluidity and pumpability of concrete, reduce resistance during construction, and reduce construction difficulty. In addition, the lubricating effect of cellulose ether can also reduce the wear of pipelines during concrete pumping and extend the service life of equipment.
4. Anti-cracking agent
Cellulose ether also has anti-cracking effect in building materials. Adding cellulose ether to gypsum products can improve the crack resistance of gypsum and prevent cracks from occurring during the drying process. In self-leveling floor materials, cellulose ethers can improve the flexibility of the material, reduce shrinkage stress, and prevent floor cracking.

5. Binder
Cellulose ether also plays an important role in bonding materials such as tile glue and putty powder. It improves the material's bonding properties, giving it good adhesion on a variety of substrates. At the same time, cellulose ether can also enhance the water resistance and weather resistance of the material, improving construction quality and durability.
6. Suspending and dispersing agents
Cellulose ethers are used as suspending and dispersing agents in architectural coatings. It can effectively prevent the precipitation of pigments and fillers and ensure the uniformity and stability of the paint. In addition, cellulose ether can also improve the construction performance of coatings, making the coating uniform and the surface smooth.
7. Construction mortar
In construction mortars, cellulose ethers are mainly used as thickeners, water retaining agents and additives to improve construction performance. It can improve the water retention of mortar, extend the opening time of mortar, and prevent cracking and strength reduction caused by rapid water loss of mortar during construction. Cellulose ether can also improve the workability of mortar, making it easier to spread and smooth the mortar, improving construction efficiency and quality.
8. Gypsum-based materials
In gypsum-based materials, cellulose ethers are mainly used to improve the water retention and construction performance of the materials. It can prevent cracks in gypsum products during the drying process and improve the strength and durability of gypsum. Cellulose ethers can also improve the fluidity and workability of gypsum, making gypsum products easier to shape and modify during construction.
9. Self-leveling floor
In self-leveling floor materials, cellulose ether is mainly used to improve the fluidity and self-leveling performance of the material. It allows the floor material to spread quickly during the construction process to form a smooth surface, while improving the water retention and strength of the material to prevent cracking and sanding of the floor.
10. Tile adhesive
Cellulose ethers are mainly used in ceramic tile adhesives to improve the water retention and bonding strength of the adhesive. It can prevent the tiles from losing water too quickly during the bonding process and ensure the bonding effect of the tiles. At the same time, cellulose ether can also improve the flexibility and weather resistance of the adhesive, making the tiles less likely to fall off and crack during use.
Cellulose ethers have a wide range of applications in the building and construction fields. As thickeners, water retaining agents, lubricants, anti-cracking agents, binders, suspending agents and dispersants, cellulose ethers play an important role in improving the construction performance, durability and quality of building materials. With the continuous development of construction technology, the application prospects of cellulose ethers in building and construction will be broader.
