Product Details
Product Description
MelaColl™ Hydroxyethyl Methyl Cellulose (HEMC), also known as Methyl Hydroxyethyl Cellulose (MHEC), is a non-ionic cellulose ether. It is made from natural polymer cellulose through a series of etherification reactions. HEMC is excellent in water solubility, water retention, surface activity, thickening, film formation, adhesion, suspension, and high-temperature resistance... Mikem’s products have been widely used in various industries, including tile adhesives, grouts, skim coat/wall putty, cement renders, gypsum-based products, cement-based mortars.

Melacoll™ MHEC Highlights
- Cold-water solubility. HEMC dissolves easily in cold water, reducing your waiting time.
- High-temperature resistance. It usually keep working under 75℃.
- Thickness. HEMC for liquid can increases viscosity and stability.
- Water retention. Extending the open time also helps cement hydration more fully.
- Lubrication. HEMC for cement can improves workability and processing.
- PH stability. HEMC remains stable in the range of pH 3~11.
- Non-ionic. HEMC is more stable in an aqueous solution.
- Thermal gelation. It turns into a gel when the temperature is too high, and when cools down, it turns into the liquid again.
- Air entraining. HEMC for mortar can help increase mortar production and improve workability.
- Film formation. HEMC cellulose is waterproof and oil-proof.
