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.

How To Use HEMC for Building & Construction?

HEMC (Hydroxyethyl Methyl Cellulose) is an important additive used in the building and construction industry to improve the performance of cementitious materials, such as mortars, grouts, and renders. Here are some general guidelines for using HEMC in building and construction:


Preparation: HEMC is typically supplied as a dry powder, which is easily soluble in water. It should be added slowly to the water while stirring to ensure proper dispersion and avoid clumping.


Mixing: Once the HEMC is fully dispersed in water, it can be added to the other ingredients, such as cement, sand, and aggregate. The mixture should be stirred thoroughly until a smooth and consistent blend is obtained.


Application: The mixed material can then be applied according to the manufacturer's instructions. HEMC can provide benefits such as improved water retention, thickening, binding, adhesion, sag resistance, flexibility, and surface smoothness to the final product.


Dosage: The optimal dosage of HEMC depends on the specific application and the desired performance characteristics. In general, a dosage of 0.1% to 0.5% by weight of cementitious materials is recommended, but it is important to follow the manufacturer's instructions and test the mixture to ensure the desired properties are achieved.


Compatibility: It is important to ensure that HEMC is compatible with the other ingredients used in the mixture. Incompatible materials may result in reduced performance or even failure of the final product.
