Product Description
Hydroxyethyl Methyl Cellulose (MHEC)
Hydroxyethyl Methyl Cellulose, MHEC is made from highly pure cotton-cellulose by reaction of etherification under alkaline conditions without any organs of animals, fat and other bioactive constituents.
It could be soluble in water to form a transparent solution and widely used in construction and building material, dry mix mortar industry. Like tile grouts, tile adhesive, white cement/gypsum based wall putty, decorative plaster as thickening agent for retaining water and improving constructability. The market for HEMC in the paint industry is growing steadily due to its wide range of benefits and its compatibility with various paint formulations. It is commonly used in both water-based and solvent-based paints, making it a versatile choice for manufacturers.
Hydroxyethyl Methyl Cellulose (HEMC) Kundu Chemicals provides is a construction grade cellulose ether that is made from natural polymer cellulose through a series of etherification reactions. Our HEMC products are excellent in water solubility, water retention, surface activity, thickening, film formation, adhesion, suspension, and high-temperature resistance, etc.
We can also offer the regular grade MHEC or the modified MHEC according to customer requirements.

Advantages of Kundu Hydroxyethyl Methyl Cellulose (MHEC) ;
● High water retention, making the moisture not easy to lose or be absorbed too quickly by the substrate.
● Thickening.
● Anti-sagging, improved mortar bonding ability.
● Better workability, mortar can be applied easier and quicker.
● Longer open time. It can extend the hardening time of the mixture, make the raw materials fully hydrated, and improve the tensile strength and flexibility of the mixture.
● Reduce air entrancement and water uptake.
● Improved adhesion and sliding resistance: especially for heavy tiles.
