Hydroxyethyl Methyl Cellulose (HEMC)
HEMC is a key cellulose ether widely used in construction materials, paints, and personal care products. It acts as a thickener, water-retention agent, and binder in tile adhesives, cement mortars, and gypsum plasters, improving workability and adhesion. In coatings and cosmetics, HEMC enhances viscosity, stability, and film-forming properties. Its excellent solubility and thermal gelation make it ideal for diverse industrial applications.
| HEMC grade | Viscosity range | Application |
| CELOSE MES series | 400-200000 mPa.s | Paints, detergent, concrete |
| CELOSE ME series | 60000-200000 mPa.s | Universal grade for dry mixed |
| CELOSE ME T series | 60000-200000 mPa.s | Modified grade for tile adhesive |
| CELOSE ME C series | 60000-200000 mPa.s | Modified grade for cement based putty |
| CELOSE ME G series | 60000- 200000 mPa.s | Modified grade for gypsum mortar |
What is HEMC?
Hydroxyethyl Methyl Cellulose (HEMC) is a non-ionic, water-soluble cellulose ether derived from natural cellulose. Through chemical modification, it exhibits excellent thickening, water retention, film-forming, and adhesive properties. HEMC is widely used in construction materials, coatings, adhesives, and personal care products due to its stability, compatibility, and adjustable viscosity.
Applications of HEMC
- Tile adhesives & cement mortars (improves adhesion & open time)
- Self-leveling compounds & renders (enhances flow & crack resistance)
- Gypsum-based products (optimizes setting time & workability)
- Water-based paints (stabilizes pigments & prevents splashing)
- Texture coatings (provides smooth application & film formation)
- Enhances bonding strength & flexibility in wood glue and ceramic adhesives
- Used in shampoos, creams, and ointments as a thickener & stabilizer
