Hydroxyethyl Methyl Cellulose(HMEC/MHEC)
Newsanda Hydroxyethyl Metal Cellulose (HEMC/MHEC) is an odorless and nontoxic white powder that SWELLS in cold water into a clear or slightly turbid colloid solution It is double in cold water and most organic solvents.Newsanda HEMC has significant thickening, water retention, and suspension stability. disability, cohesiveness, film-forming properties, etc. In the construction industry, Newsanda HEMC can be used as a thickener and water retention agent in the formula of tile adhesives, grooves, self-leveling compounds, influencing and bonding mortars for ELFS/ETICS, Gypsum plates, and so on.
Features
|
Thickening Effect |
Newsanda HEMC is used very often as a thickener in building applications as it prevents segregation and improves the cohesion of the formulation components. The addition of Newsanda cellulose ether imparts excellent stickiness to wet mortar can increase the adhesion of wet mortar to the base layer and improve the sag resistance of the mortar.
|
Water Rentention |
Newsanda HEMC can be used as a water retention agent in building materials. hemc can effectively prevent too fast and low penetration of water into the base surface in cement-based products, allowing more water to stay in the mortar and participate in the cement hydration reaction. Compared with HPMC, HEMC has a higher gel temperature development.
|
Easy workability |
Newsanda HEMC is widely used as an additive to building chemicals and it commits improved open time, lubrication , and assistance to sagging for cement-based or gypsum-based dry mix mortars, to realize easy workability.
