KimaCell® HEMC MH150M hydroxyethyl methylcellulose, as a kind of cellulose ether, has become more and more popular in the construction industry in recent years because of its excellent performance in the building materials industry and its small addition amount and great use.
HEMC can be used as retarder, water retaining agent, thickener and binder. HEMC can play an important role in ordinary dry-mixed mortar, external wall insulation mortar, self-leveling mortar, tile adhesive, internal and external wall putty, caulking agent and other materials. HEMC has an important influence on the water retention, water addition, construction, cohesion and retardation of the mortar system. Different types of hydroxyethyl methylcellulose are used in different mortar systems according to their own characteristics.

KimaCell® HEMC MH150M hydroxyethyl methyl cellulose is one of the important cellulose ether admixtures in dry powder mortar, hydroxyethyl methylcellulose has many functions in mortar. The most important function of hydroxyethyl methylcellulose in cement mortar is water retention and thickening. In addition, due to its interaction with the cement system, it can also play an auxiliary role in entraining air, retarding setting, and improving tensile bond strength. effect.
The most important performance of HEMC in mortar is water retention. As a cellulose ether admixture in mortar, HEMC can be used in almost all mortar products, mainly because of its water retention. Generally speaking, the water retention of HEMC is related to its viscosity, degree of substitution and particle size.
Hydroxyethyl methyl cellulose is used as a thickener, and its thickening effect is related to the degree of substitution, particle size, viscosity and degree of modification of hydroxyethyl methyl cellulose. Generally speaking, the higher the degree of substitution and viscosity of cellulose ether, and the smaller the particles, the more obvious the thickening effect.
