WOTAI HEMC Details
HEMC, aka hydroxyethyl methyl cellulose. Also called MHEC, it is short-term for methyl hydroxyethyl cellulose. It’s produced from a natural renewable polymer, wood pulp, or refined cotton. It is a non-ionic cellulose ether that evolved from the addition of 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.
WOTAI Hydroxyethyl methylcellulose is widely used in tile adhesives, dry mix mortar, joint filler, wall putty/skim coat, self-leveling floor, gypsum plaster, EIFS, and detergent. As China’s professional HEMC manufacturer and supplier, WOTAI Chemical supports your business with different types of HEMC of various applications. Besides that, WOTAI R&D Center manages to create customized HEMC formulas to meet your particular requirements.
HEMC by Application
WOTAI Hydroxyethyl methylcellulose contributed to many aspects of our life and environment. With premium quality at reasonable prices. Let’s discover more!
HEMC for dry mix mortar increases pumping ability and makes the mortar easy to apply. Maintain enough mosture in the mortar and reach best performance.
HEMC for tile adhesive significantly improves compatibility and stickiness, reduce moisture evaporation, makes the tiles firmly attach to the wall or floor, without sagging or sliding.
HEMC for joint filler is pretty stable and durable even at high temperatures, particularly applicable in hot weather, strong cohesiveness boost construction performance.
HEMC for wall putty/skim coat is a universal building material for both interior and exterior walls. WOTAI HEMC restrains water loss and maintain a cartain level of moisture.
EIFS is the short form of Exterior Insulation and Finish Systems. HEMC in EIFS provide adhering strength with good consistency, sag resistant. Make construction process easier
Detergent grade HEMC quickly dissolved in cold water, acted as an efective colloidal protective agent, thickener, emulsifier and dispersant, good viscosity stability during long-term storage.
HEMC by Grades
WOTAI Chemical provide you with various grades hydroxyethyl methylcellulose for construction and household. They have different viscosity levels. HEMC with high viscosity are mainly used for thickening, foaming, adhesion to improve water retention effect. Low viscosity HEMC are particularly used in dispersion and suspension.

FAQ
Have any questions? We’re here to help you out.
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. WOTAI HEMC is applicable in dry mix mortar, tile adhesive, wall putty/skim coat, self leveling etc.
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.
Hydroxyethyl methylcellulose is obtained from wood pulp or refined cotton, it’s natural resources.
HEMC is soluble in both hot and cold water.
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.
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.
Avoid direct sunlight and humidity.
Keep in cool and dry condition.
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.
