HEMC stands for Hydroxyethyl Methyl Cellulose. It is a non-ionic cellulose ether that is widely used in the building and construction industry as a thickener, binder, and water retention agent.
HEMC is modified with both methyl and hydroxyethyl groups, which makes it water-soluble and provides it with unique properties that are useful in building and construction applications.
In building and construction, HEMC is used in a variety of products, such as cement-based mortars, tile adhesives, and grouts. It improves the performance of these products by providing them with the following properties:
Water retention: HEMC can hold onto water in a mortar, preventing it from drying out too quickly and allowing it to cure properly. This improves the strength and durability of the mortar.
Thickening: HEMC can thicken the mortar or adhesive, providing it with better workability and reducing sagging or slumping during application.
Binding: HEMC can bind the ingredients in the mortar or adhesive, improving the overall cohesiveness and preventing separation or segregation of the components.
Improved adhesion: HEMC can improve the adhesion of the mortar or adhesive to the substrate, providing a stronger and more reliable bond.
