HEMC powder is made from natural polymer cellulose. It provides many of the same benefits as other methylcellulose derivatives.


Our HEMC cellulose excels in water retention and improves adhesion. It has great film formation for construction projects. WOTAIchem™ HEMC powder is a safe, strong, and resistant product you can depend on.


  • Water retention and adhesive power.
  • High-temperature resistance.
  • Dispersant and suspension ability.
  • Perfect thickener and film formation agent.

WOTAIchem HEMC for Building Materials

MHEC’s full form is methyl hydroxyethyl cellulose, aka HEMC. It’s produced from a natural renewable polymer, wood pulp, or refined cotton. It is a non-ionic cellulose ether that evolved from adding ethylene oxide to methylcellulose.


HEMC can be white to off-white powder, but it’s odorless regardless of color, safe for all animal species, and environmentally friendly. The main methyl hydroxyethyl cellulose uses is in tile adhesives, dry mix mortar, joint filler, wall putty/skim coat, self-leveling floor, gypsum plaster, EIFS systems.

How to Test Viscosity of HEMC Powder?
How do you measure your HEMC? Do you have viscosity 200000 for tile adhesive?

HEMC for tile adhesives is Brookfield Viscometer 75,000mPa.s, equivalent to NDJ viscosity 200,000 mPa.s.


The HEMC Brookfield Viscometer is a standard tool for measuring viscosity. It ranges from 0.1 to 100,000 mPa.s, with an accuracy of ±0.5%. The HEMC Brookfield viscometer is also available in models with higher viscosity ranges, such as the HEMC-100K, which ranges from 100,000 to 1,000,000 mPa.s.


Different applications require different levels of viscosity for cellulose ethers. Our team can provide the conversion chart between NDJ measurements and Brookfield viscometers. This chart ensures you’re using the proper amount of cellulose ether for your specific needs.

Can you produce different packaging sizes according to my needs?

Yes! WOTAIchem offers customized packaging services for our chemical products. You can choose to select different sizes based on your requirements.


Additionally, we have a dedicated design team to support your packaging needs. You can opt for having your logo printed on the final packaging, or we can assist you in designing.

What are hydroxyethyl methylcellulose uses?

HEMC hydroxyethyl methylcellulose is widely used in construction, building materials, household. It’s a perfect water retention agent. Good water solubility, strong cohesiveness, dispersant and suspension. In construction. WOTAIchem HEMC is applicable in dry mix mortar, tile adhesive, wall putty/skim coat, self leveling etc.

Is it safe if accidentally consume hydroxyethyl methylcellulose?

HEMC is non-toxic, and it’s approved to be used as food additives, provided under a certain dosage. Excessive amount may cause irritation or other harmful effects.

Is hydroxyethyl methylcellulose natural or synthetic?

Hydroxyethyl methylcellulose is obtained from wood pulp or refined cotton, it’s natural resources.

Does hydroxyethyl methylcellulose dissolve in water?

HEMC is soluble in both hot and cold water.

What are the side effects of hydroxyethyl methylcellulose?

HEMC is safe to use as a food additive and medicine coating but depends on a certain amount. Over dosage may cause irritation or other harmful effects.

What is the difference between HPMC and HEMC?

The major difference between HPMC and HEMC is gel temperature.

HPMC at around 60°C~75°C and HEMC >80°C normally. It depends on different production technology as well. In summer, HEMC water retention capacity remains the same viscosity and dosage, especially in hot weather like in India. HPMC with lower gel temperature will lose thickening and water retention effect in a hot environment, therefore accelerating the hardening of mortar.

HPMC uses fine cotton as raw material to go through the alkalization process, plus etherification agents propylene oxide and methyl chloride, then formulate a non-ionic cellulose ether HPMC.

The production process of HEMC is similar to that of HPMC, the only difference is etherification agents, instead of propylene oxide and methyl chloride, HEMC uses ethylene oxide and methyl chloride. Because ethylene oxide requires more advanced production technology, and due to its storage condition, risk control, and less manufacturer, thus the price of HEMC is higher.

How do you store HEMC?

Avoid direct sunlight and humidity.

Keep in cool and dry condition.

Do you test your product before delivering them to your customers?

Of course we do. This falls under our QA procedure, we always test our products before sending them away. we ensure every batch is at tip-top standard.
