Hydroxyethyl Methyl Cellulose
HEMC & MHEC
Kemox HEMC is a different kind of cellulose ether from HPMC. The substitute groups of HEMC are hydroxypropyl and methoxy,Compared with HPMC, HEMC has more hydrophilic groups, which means it has a relatively high gel temperature, better water retention in hot environments, and better thermal sta-bility.
Kemox hydroxyethyl methyl cellulose(HEMC or MHEC) provides many of the same benefits as other methylcellulose derivatives, such as the ability to efficiently thicken and provide water retention, are highly effective additives used to improve the quality and processing characteristics of building materials such as plasters and renders, mortars, tile adhesives, joint compounds and emulsion paints.

HEMC Asked Questions
When choosing HEMC viscosity, consider the specific requirements of your application, such as desired consistency, water retention, and overall performance. Consult the Kemox’s guidelines to make an informed decision.
HEMC grades are differentiated based on their viscosity, which is typically measured in mPa·s (millipascal-seconds) or cP (centipoise). Different grades offer varying performance characteristics, such as water retention, solubility, and thickening ability.
When selecting HEMC, consider the specific application area and performance requirements, including viscosity, solubility, and water retention properties.
Yes, HEMC can be combined with other cellulose ethers, such as HPMC or HEC, to achieve desired properties in a specific application. The compatibility and performance of combined products should be tested before use to ensure optimal results.
Yes, HEMC is compatible with various types of cement, including Portland cement, slag cement, and fly ash cement. Its benefits and performance may vary slightly depending on the cement type and formulation.
HEMC is biodegradable and has minimal environmental impact during its use and disposal, making it an eco-friendly material.
