2-hydroxyethyl methyl cellulose
2-hydroxyethyl methyl cellulose Quick Details
Chemical Name: 2-hydroxyethyl methyl cellulose
Appearance: white or off-white powder, odorless and tasteless.
Particle size: the passage rate of 100 meshes is more than 98.5%; and 80 meshes is 100%.
Apparent density: 0.30-0.60g/cm3.
Solubility: It is soluble in water and some organic solvents. It can be dissolved in cold water. And solubility varies with the viscosity. The lower the viscosity, the higher the solubility. HEMC with the surface treatment will disperse in cold water, not to agglomerate, and slowly dissolve. However, if the pH value is adjusted to 8-10, it can be quickly dissolved.

2-hydroxyethyl methyl cellulose Usage
With its thixotropy and easy to close, mortar has a pumping. At the same time, it can improve the ability of resisting vertical flow and high water retention. Also it can prolong the working time of mortar and help form high mechanical strength of mortar in solidification.
Gypsum plaster and gypsum products
As a binder, its thixotropy and coagulation can improve and extend the operational time of painting. With its water retention, the slurry after smearing will not dry too fast and crack, but increase strength after hardening.
Masonry mortar can enhance adhesion with the surface and ability to retent water, so as to increase the strength of cement mortar. It also can increase the lubrication and plasticity to improve the performance of construction
With excellent water retention, lubricity, high resistance to shrinkage and crack resistance, it can provide smooth and uniform texture of the material to ensure the bonding surface adhesion.
It is widely used as a binder in the manufacture of ceramic products.
Self-leveling floor material
With its improved fluidity and pumpability, it can improve the efficiency of grounding, control water retention, thus greatly reduce the cracking and shrinkage.
Extrusion of formed concrete plate
With high adhesive strength and lubrication, it can enhance processing properties of extrusion products. It can improve wet strength and adhesiveness after extrusion.
