Product Description
Hydroxypropy Methyl Cellulose Ether (HPMC) is widely used as a thickener, stabilizer and water retaining agent for building materials. It provides water retention and workability for mortars, it can improve adhesion, reduce skinning and increase open time.
Hydroxypropy Methyl Cellulose Ether (HPMC) is a highly pure cotton cellulose as raw material, under alkaline conditions by special etherification and preparation.White or whitish powder.HPMC decreases with the decrease of methoxide content, increase of gel point, decrease of water solubility and decrease of surface activity.
Hydroxypropy Methyl Cellulose Ether (HPMC) has thickening ability, salt resistance, low ash powder, pH stability, water retention, dimensional stability, excellent film forming, and a wide range of enzyme resistance, dispersion and adhesion.
In the course of construction,HPMC is used for wall putty, tile adhesive, cement mortar, dry mix mortar, wall plaster, skim coat, mortar, concrete admixtures, cement, gypsum plaster, joints fillers, crack filler, etc.
Water Retention:The water retention will be enhanced, which is helpful with such problems as cement or gypsum construction.
Adhesivity:It can make mortar attach to base material better sincethe plasticity of mortar is enhanced.
Operationality:It can enhance the plasticity of mortar and improve the coating efficiency in construction projects
Different viscosity for different application,we can accept OEM.

Choosing different varieties, different viscosities, different particle sizes, different degrees of viscosity and addition amount of hydroxypropyl methyl cellulose will also have different effects on the improvement of the performance of dry mortar.
The working principle of dry powder additive HPMC:
The hydroxyl group on the molecule and the oxygen atom on the ether bond will associate with the water molecule to form a hydrogen bond, so that free water becomes bound water, which plays a good role in water retention. |
HPMC is widely used in building materials, coatings, synthetic resins, ceramics, daily chemicals, textiles, oil fields, plastics and other industries, with high technical content and high added value.

Hydroxypropyl Methyl Cellulose Ether(HPMC) is mainly used in the dry building materials from the construction industry, including the water-resistant putty powder, putty paste, steel putty, paint glue, thermal insulation mortar and so on. It has a good water retention effect, and it is easy to be constructed with a good luminosity, besides, the viscosity and gel time can be customized according to the requirement of customers.
Cement Plaster / Dry mix mortar
Easy dry mix formula due to cold water solubility: lump formation can be easily avoided, ideal for heavy tiles. Good water retention: prevention of fluid loss to the substrates, the appropriate water content is kept in mixture which guarantees longer concreting time. Increased water demand: increased open time, expanded spry area and more economical formulation. Easier spreading and improved sagging resistance due to improved consistency.
Wall putty
Water retention: maximized water content in slurry. Anti-sagging: when spreading a thicker coat corrugation can be avoided. Increased mortar yield: depending on the weight of the dry mixture and appropriate formulation ,HPMC can increase the mortar volume.
Exterior Insulation and Finish System ( EIFS )
Improved adhesion. Good wetting ability for EPS board and substrate. Reduced air entrancement and water uptake.
Self-leveling Mortar
Protection from water exudation and material sedimentation. No effect on slurry fluidity with low viscosity HPMC, while its water retention characteristics improve the finish performance on the surface.
Crack Filler
Better workability: proper thickness and plasticity. Water retention ensures prolonged work time. Sag resistance: improved mortar bonding ability.
