Hydroxypropyl Methyl Cellulose



Kemox HPMC is a non-ionic, water soluble cellulose ether which offers a variety of functional properties when dissolved in water. It can be used as thickeners, binders, surfactants, protective colloids, suspending agents and water retention agents.

Kemox hydroxypropyl methyl cellulose(HPMC) is the selection of pure refined cotton as raw material,with propylene oxide and chloromethane as etherifying agent,under alkaline conditions through etherification of non-ionic cellulose etheris a tasteless,non-toxic white or white powder,can dissolve in cold water,swelling into transparent or slightly turbid colloidal viscous solution,the degree of substitution is generally 1.2-2.0. Its properties are subject to the proportion of methoxy content and hydroxypropylcon-tent,and there are differences. Main ingredientsicotton,methyl chloride,propylene oxide,caustic soda liquid.

Functions & Specifications

Water Retention
Enhance water retention, improve cement, gypsum building materials too fast drying and hydration caused by poor hardening, cracking and other phenomena.
Improve Workability
Increase the mortar plasticity, improve the construction of industrial coating, improve work efficiency;
Due to the improvement of mortar plasticity, so that it can better bond the substrate and be bonded;
Because of its thickening effect, it can prevent the occurrence of slippage of mortar and bonded objects during construction.

HPMC Asked Questions​

HPMC is mainly used in tile adhesives, wall putty, cement-based mortars, gypsum-based mortars, self-leveling floors, and external wall insulation mortars.

When selecting HPMC, consider the specific application area and performance requirements, including viscosity, solubility, and water retention properties.

The usage method mainly involves gradually adding HPMC to water while stirring until fully dissolved. Precautions include avoiding adding too much HPMC at once to prevent clumping.

Yes, HPMC can be mixed with various additives, such as redispersible polymer powder, cellulose ethers, and defoamers, depending on the specific application requirements.

HPMC should be stored in a dry, cool, and well-ventilated environment, avoiding direct sunlight and high temperatures.

When transporting HPMC, ensure the packaging is intact and undamaged, avoid moisture and heat exposure, and do not mix with toxic or hazardous items.
