KimaCell® HEMC MH400 hydroxyethyl methyl cellulose can be used in cement-based materials to regulate physical and mechanical properties, such as improving cement mortar workability, water retention, bonding performance, setting time, flexibility, etc. But it will also significantly reduce the mechanical properties of cement mortar such as compressive strength. Cement as a cementitious material, its degree of hydration and the type and quantity of hydration products are one of the main factors affecting the performance of cement-based materials.

KimaCell® HEMC MH400 is widely used in self-leveling compound flooring materials.
HEMC is a multi-group ether mixed with methoxy and hydroxyethoxy. Compared with hydroxypropoxy, the biggest feature of hydroxyethoxy is that it will not have a gel point with temperature changes, such as HPC and MC All have gel points, while HEC has no gel point. Experiments have proved that HEMC has a gel point, but it is relatively high, and as the content of hydroxyethoxy increases, its gel point moves to the direction of high temperature. If it is used in mixed mortar, it is beneficial to delay the cement paste at high temperature. Besides, it can also be used in food, paint, medical dressing and other fields, and it also shows superior performance. The scale of domestic mass production is small, the quality fluctuates, and the products are not standardized. Therefore, optimizing the preparation process of HEMC and realizing quantitative manufacturing has great potential
