Hydroxyethyl Methyl Cellulose (MHEC) are water soluble nonionic cellulose ethers, which are offered as free flowing powder or in granular form cellulose.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.MHEC appears to be white powder and is odorless and tasteless. It is featured by hygroscopicity and hardly soluble in hot water, acetone, ethanol and toluene. In cold water MHEC will swell into colloidal solution and its solybility is not influenced by PH value.Similar to methyl cellulose while being added to Hdroxyethyl groups. MHEC is more resistant to saline, easily soluble in water and has higher gel temperature.
Mortar and Cement Additive:
MHEC acts as a thickening agent in mortar and cement formulations, enhancing workability and adhesion.
It improves water retention, preventing premature drying and ensuring proper hydration of cementitious materials.
Its ability to form a protective film over surfaces helps in reducing dust formation and improving surface finish.
Tile Adhesives and Grouts:
MHEC is incorporated into tile adhesives to improve their bonding strength and prevent sagging.
It enhances the consistency of grouts, facilitating their application and ensuring uniform filling of gaps between tiles.
Exterior Insulation and Finishing Systems (EIFS):
In EIFS applications, MHEC serves as a rheology modifier, controlling the flow properties of coatings and improving their application characteristics.
Self-Leveling Flooring Compounds:
MHEC imparts viscosity and stability to self-leveling flooring compounds, enabling smooth and even application over large surfaces.
