Hydroxyethyl Methyl Cellulose
Methyl hydroxyethyl cellulose is agelling and thickening agent derivedfrom cellulose. The solution presentsstrong pseudoplasticity and provides high shear viscosity. lt is mainly used as dispersant, ad- hesive protective colloid, thickenerand stabilizer for coatings, building materials and daily cosmetics, Hydroxyethyl methyl cellulose HEMC is mainly used in tile adhesives, roll-on/ wallputty, cement coatings, gypsum-based products, cement-based mortars, wa-ter-based emulsion coatings and drilling oils.
Hydroxyethyl methylcellulose offers many of the same benefits as other methylcellulose derivatives, such as the ability to thicken effectively and provide water retention. Hydroxyethyl methylcellulose is used to improve the quality and processing properties of highly effective additives for building materials such as mortars and plasters, mortars, tile adhesives, putties, putties, joints and even latex paints.
HEMC is widely used in water-based emulsion coatings, construction building materials, printing ink, oil drilling and other fields, playing the role of thickening, water retention, improve the ease of use. It is used as gelling agent and water-retaining agent for cement, gypsum and lime, and is an excellent additive for powder construction materials. Used as an additive for toothpaste, cosmetics, detergent, etc.

FAQ
What is the use of hydroxyethyl methylcellulose?
HEMC Hydroxyethyl methylcellulose is widely used in construction, building materials, and home furnishing. It is a perfect water retaining agent. It has good water solubility, strong adhesion, dispersant and suspending agent. In construction. HEMC is suitable for dry-mixed mortar, tile adhesives, wall putty/putty coating, self-leveling, etc.
Is hydroxyethyl methylcellulose soluble in water?
HEMC is soluble in hot and cold water.
What is the difference between HPMC and HEMC?
The main difference between HPMC and HEMC is the gel temperature.
HPMC is generally around 60°C~75°C, and HEMC is generally above 80°C. It also depends on different production processes. The water retention capacity of HEMC in summer is unchanged with viscosity and dosage, especially in hot weather such as India. HPMC with a lower gel temperature will lose its thickening and water retention effect in a hot environment, thereby accelerating the hardening of mortar.
HPMC is made of refined cotton, which is alkalized and added with etherifying agents propylene oxide and methyl chloride to produce non-ionic cellulose ether HPMC.
The production process of HEMC is similar to that of HPMC, the only difference is the etherifying agent, HEMC uses ethylene oxide and methyl chloride instead of propylene oxide and methyl chloride. Since the production process of ethylene oxide is more demanding, and there are fewer storage conditions, risk control, and manufacturers, the price of HEMC is higher.
