Product Details

Product Description

Hydroxyethyl Methyl Cellulose (HEMC), also known as Methyl Hydroxyethyl Cellulose (MHEC), is a non-ionic cellulose ether. It is made from natural polymer cellulose through a series of etherification reactions. HEMC is excellent in water solubility, water retention, surface activity, thickening, film formation, adhesion, suspension, and high-temperature resistance... Mikem’s products have been widely used in various industries, including tile adhesives, grouts, skim coat/wall putty, cement renders, gypsum-based products, cement-based mortars.

Chinacel HEMC/MHEC Highlights

Cold-water solubility.
High-temperature resistance.
Salt resistance
Surface activity: Since the aqueous solution has surface activity, it can be used as a colloid protective agent, emulsifier and dispersant
Thermal gelation. HPMC turns into a gel when the temperature is too high, and when cools down, it turns into the liquid again.
Water retention: The product has hydrophilicity and high viscosity of its aqueous solution, and is a highly efficient water retention agent
Other properties: thickener, film former, adhesive, lubricant, suspending agent, protective colloid, emulsifier, etc.

MHEC Application 

Building Grade Methyl Hydroxyethyl Cellulose (MHEC) is a versatile non-ionic cellulose ether widely employed in the construction industry. This white powder or granule, known for its odorless and tasteless nature, is synthesized through a series of etherifications. Building Grade MHEC is recognized for its multifaceted properties that contribute significantly to the enhancement of various building materials. Its primary functions encompass thickening, adhesion, dispersion, emulsification, film formation, suspension, adsorption, surface activity, moisture retention, and salt resistance.

Thickening and Adhesion Properties

One of the key attributes of Building Grade MHEC is its remarkable thickening capability. When incorporated into formulations, it imparts viscosity to the materials, enhancing their consistency and workability. This property is particularly advantageous in the production of masonry mortar, gypsum mortar, and self-leveling mortar. Additionally, MHEC acts as an excellent adhesive agent, promoting better bonding between different components of building materials. This ensures improved strength and durability in the final construction products.

Dispersion, Emulsification, and Film Formation

Building Grade MHEC plays a crucial role in dispersion and emulsification processes during the production of construction materials. By aiding in the uniform distribution of particles and facilitating the formation of stable emulsions, MHEC ensures homogeneity in the end products. Moreover, its film-forming characteristics contribute to the creation of a protective layer, enhancing the resistance of materials to environmental factors and ensuring long-term structural integrity.

Moisture Retention, Suspension, and Salt Resistance

The moisture retention property of Building Grade MHEC is particularly beneficial in preventing premature drying of construction materials, allowing for extended working times. Its ability to maintain a stable suspension of particles further enhances the overall performance of products such as ceramic tile adhesives. Additionally, MHEC exhibits excellent resistance to salt, making it a valuable component in formulations designed for applications in challenging environments, where exposure to saline conditions may compromise the quality of traditional construction materials. Overall, Building Grade MHEC stands as an indispensable additive in the construction industry, contributing to the improved functionality and durability of a wide range of building materials.
