Hydroxyethyl Methyl Cellulose (HEMC), alternatively referred to as Methyl Hydroxyethyl Cellulose (MHEC), is a non-ionic cellulose ether synthesized from natural cellulose polymers. Renowned for its thickening, water retention, and film-forming properties, HEMC finds extensive application across construction materials, surface coatings, and everyday consumer products.

HEMC is widely incorporated into tile adhesives, wall putties, ready-mix mortars, joint fillers, gypsum-based plasters, and self-leveling floor compounds. In these products, it significantly enhances water retention, adhesive strength, overall workability, and material consistency.

While both HEMC and Hydroxypropyl Methyl Cellulose (HPMC) belong to the family of cellulose ethers, HEMC is distinguished by its hydroxyethyl side groups rather than hydroxypropyl. This structural difference endows HEMC with superior water retention capabilities and greater thermal stability, making it particularly advantageous for applications in hot climates or environments exposed to elevated temperatures.

LANDERCOLL™ HEMC is offered in a broad spectrum of viscosity grades—ranging from 400 mPa·s up to 100,000 mPa·s (Brookfield RV, 2%)—providing flexibility to select the most suitable grade for your specific formulation requirements and intended application.

HEMC powder should be kept in a cool, dry, and well-ventilated location, shielded from direct sunlight and humidity. Once a package is opened, reseal it tightly to prevent clumping or contamination. Notably, HEMC is non-toxic, non-corrosive, and environmentally safe, allowing for routine industrial handling without special precautions.

Absolutely. The LANDU research and development team delivers bespoke HEMC formulations tailored to meet distinct project specifications or market demands. Whether you require modifications in viscosity, setting time, or water retention properties, our specialists can engineer an individualized solution to ensure optimal product performance.
