Hydroxyethyl Methylcellulose - HEMC/MHEC

MikaZone hydroxyethyl methyl cellulose (HEMC), also known as methyl hydroxyethyl cellulose (MHEC), is a non-ionic cellulose ether derived from natural polymer cellulose. Our HEMC powder offers many of the same benefits as other methylcellulose derivatives, excelling in water retention, adhesion, and film formation. It is a safe, strong, and reliable product, ideal for construction projects and various other applications.

Features

Mikazone® HEMC has significant thickening, water retention, suspension stability, dispersibility, cohesiveness, film-forming properties, etc.

Thickening Effect

Mikazone® Hydroxyethyl Methyl Cellulose (HEMC) is widely used as a thickener in building applications. It enhances cohesion, prevents segregation, and improves the adhesion and sag resistance of wet mortar.

Water Rentention

Mikazone® HEMC acts as a water retention agent in building materials, preventing rapid water loss and ensuring proper cement hydration. It has a higher gel temperature than HEMC.

Easy workability

Mikazone® Hydroxyethyl Methyl Cellulose (HEMC) is widely used in building chemicals to enhance open time, lubrication, and sag resistance in cement-based or gypsum-based dry mix mortars, ensuring easy workability.

HPMC or HEMC?

HPMC and HEMC have certain differences due to the variations in their chemical substituents, leading to different gel temperatures and consequently, distinct recommended applications in various scenarios.

Substituent differences

HPMC and HEMC are two commonly used cellulose ether compounds with different substituents.

（Hydroxypropyl Methyl Cellulose）HPMC：contains hydroxypropyl and methyl groups in its molecules

（Hydroxyethyl Methyl Cellulose）HEMC： HEMC contains hydroxyethyl and methyl groups

gelation temperature differences

Due to the difference in chemical structure, there is a difference in gelation temperature performance between HEMC and HPMC.

（Hydroxypropyl Methyl Cellulose）HPMC：55-75℃

（Hydroxyethyl Methyl Cellulose）HEMC： 75-100℃

Differences in application scenarios

The higher gelation temperature of HEMC makes it more suitable for use in environments with higher construction temperatures.

MikaZone Recommended HEMC Grade

To meet the needs of different regions, industries, and applications, we have developed and supply two series of HEMC products: the E series, which is untreated HEMC, and the ES series, which is surface-treated HEMC.

In addition, for customers pursuing superior quality with sufficient budgets, we offer the ER and EL product lines, which have been enhanced in terms of open time and slip-resistance performance.

Professional HEMC/MHEC Solutions For the Top 6 Uses

HEMC for Tile Adhesive

When used in tile adhesive, HEMC/MHEC greatly enhances compatibility and adhesion, minimizes moisture loss, and ensures tiles adhere securely to walls or floors, preventing any drooping or shifting.

HEMC for Gypsum Plaster

Incorporating MHEC into gypsum plaster simplifies handling, enhances ponding performance, reinforces the plaster, and slows down excessive drying. This addition facilitates workability, improves water retention, boosts plaster durability, and regulates drying rates effectively.

HEMC for Skim Coat / Wall Putty

MHEC used in wall putty/skim coat serves as a versatile construction material suitable for both interior and exterior walls. WOTAIchem HEMC helps retain moisture and prevents excessive water loss, ensuring a consistent level of dampness.

HEMC for Self Leveling

Self-leveling compounds with MikaZone HEMC highly improve the rheology and workability of full ranges of flooring formulations, MikaZone HEMC leads to better leveling properties and excellent com pressive strength, which are the key requirements for self-leveling compounds.

HEMC for Joint Filler

In joint filler applications, HEMC exhibits stability and durability even under high temperatures, especially in hot weather conditions. Its strong cohesion enhances construction efficiency, simplifying the building process.

HEMC for Spray Plasters

The most significant advantage of spray plaster is its high construction efficiency and high plaster quality after molding. Since it has a higher initial speed during spraying, it can have a relatively firm grip on the substrates, which can effectively avoid hollowing and cracking.

HEMC Packaging

We have an automated production packaging assembly line where every step, from filling, weighing, sealing to loading, is guided by operational standards, all of which are carried out within our factory.

Custom Packaging

Custom HEMC packaging and OEM are both supported. Contact Mikazone for more information on custom services.

500Kg / 1MT per Pallet

Mikazone HEMC is packaged and shipped in 500kg per pallet. We also offer custom services if you have special requirements.

25Kg per Bag

We use high-quality polypropylene woven bags to package HEMC, preventing moisture-induced clumping during transportation.

How to purchase surface-treated HEMC and untreated HEMC?

If a delayed thickening is needed for uniform dispersion and longer working time in the application, surface-treated HEMC should be chosen.

If quick thickening of the material is required in the application, untreated HEMC should be selected.

Are the performance characteristics of HEMC and HPMC the same?

HEMC has a higher gel temperature and is more suitable for high-temperature construction environments.

Are there any other surface-treated HEMC types with different viscosities besides MK200ES and MK100ES?

We can customize products with different viscosities according to customer requirements, and the initial adhesion time can also be customized.

Do I need to pay for shipping or taxes for the samples?
