Hydroxyethyl methyl cellulose (HEMC)
It is a non-ionic cellulose ether made from natural polymer cellulose by a series of etherification. It is an odorless, tasteless, non-toxic white powder or particles. It dissolves in hot and cold water to form a transparent, viscous solution, insoluble in common organic solvents, and solubility is not affected by pH value. It has the properties of thickening, adhesion, dispersion, emulsification, film forming, suspension, adsorption, surface activity, moisture retention and salt resistance.
Feature:
High transparency and viscosity
Good Water retention
Long open times
Highly sag resistance
widely used for Tile adhesive, Wall Putty, Panel & Block jointing and Cement Mortar, Gypsum plaster etc.
Application Specific:
(1) In the field of construction, HEMC is used for wall, plaster, caulking and other mechanized construction, suitable for concentrated dry mixing and premixed m…
