HEMC / MHEC
(Hydroxypropyl Methyl Cellulose)
Hydroxyethyl Methyl Cellulose (HEMC or MHEC) is a non-ionic, water-soluble polymer derived from cellulose. It is a white or off-white powder that is odorless and tasteless. HEMC is made by modifying natural cellulose through a chemical reaction that introduces hydroxyethyl and methyl groups onto the cellulose molecule. This modification enhances the water retention and thickening properties of the cellulose, making it more useful in a variety of applications.

Applications in Construction Industry
Mortar Mixes: HEMC is added to cement-based mortar mixes to improve their workability, water retention, and bonding properties. By increasing the viscosity of the mix, HEMC helps to prevent segregation and bleeding, and also reduces the amount of water required, resulting in a stronger, more durable mortar.
Tile Adhesives: HEMC is commonly used in tile adhesives to improve their workability, adhesion, and water retention. It also helps to prevent the formation of cracks and ensures that the adhesive has a uniform texture and consistency.
Grouts: HEMC is added to grouts to improve their flow properties, prevent shrinkage, and enhance their water retention capacity. This results in a stronger and more durable grout that is less prone to cracking or shrinking over time.
Self-leveling（EIFS/ETICS）Compounds: HEMC is used in self-leveling compounds to improve their fluidity and leveling properties. It also helps to control the drying time and prevents the formation of bubbles or voids.
Stucco: HEMC is used in stucco to improve its water retention, workability, and adhesion properties. It also helps to reduce cracking and improve the overall quality of the finish.
