Application of Hydroxypropyl Methyl Cellulose (HPMC) in Building Materials


Hydroxypropyl methyl cellulose (HPMC) is a non-ionic cellulose ether made from natural polymer material cellulose through a series of chemical processing. They are an odorless, tasteless, and non-toxic white powder that swells in cold water into a clear or slightly turbid colloidal solution. It has the characteristics of thickening, bonding, dispersion, emulsification, film formation, suspension, adsorption, gelation, surface properties, moisture retention, and protective colloid. Hydroxypropyl methyl cellulose and methyl cellulose can be used in building materials, paint industry, synthetic resin, ceramic industry, medicine, food, textile, agriculture, daily chemical, and other industries.


The main application of hydroxypropyl methyl cellulose HPMC in building materials:

1. Cement-based plaster

①Improve the uniformity, make the plaster easier to be applied on the trowel, and at the same time improve the anti-sagging property, enhance the fluidity and pumpability, and improve the work efficiency.

②High water retention, prolong the storage time of the mortar, improve work efficiency, and facilitate the hydration and solidification of the mortar to produce high mechanical strength.

③Control the introduction of air to eliminate cracks on the coating surface and form an ideally smooth surface.

2. Gypsum-based plaster and gypsum products 

①Improve the uniformity, make the plaster easier to be applied on the trowel, and at the same time improve the anti-sagging property, enhance the fluidity and pumpability, and improve the work efficiency. ②High water retention, prolong the storage time of the mortar, improve work efficiency, and facilitate the hydration and solidification of the mortar to produce high mechanical strength. 

③Control the consistency of the mortar to form an ideal surface coating.

3. Masonry mortar

①Enhance the adhesion to the surface of the masonry, enhance the water retention and improve the strength of the mortar.

②Improve lubricity and plasticity, and improve workability; using mortar improved by cellulose ether makes construction easier, saves construction time, and reduces construction costs.

③ Cellulose ether with super high water retention, suitable for high water absorption bricks.

4. Plate joint filling material

①Excellent water retention, extending open time, and improving work efficiency. High lubricant, easier to mix.

②Improve shrinkage resistance and crack resistance, and improve coating surface quality.

③Improve the adhesion of the bonding surface and provide a smooth and smooth texture.


5. Tile adhesive

①Easy to dry mix the ingredients without producing clumps, increase the application speed, improve construction performance, save working time, and reduce working costs.

②By extending the opening time, the efficiency of the tiling is improved and an excellent adhesion effect is provided.

6. Self-leveling floor material

①Provide viscosity and can be used as an anti-settling additive.

②Enhance the pumpability of fluidity and improve the efficiency of paving the floor.

③Control water retention and shrinkage, reduce ground cracking, and shrinkage.

7. Water-based paint

①Prevent solid precipitation and extend the container period of the product. High biological stability, excellent compatibility with other components.

②Improve fluidity, provide good splash resistance, sag resistance, and leveling, and ensure an excellent surface finish.


8. Wallpaper powder

①It dissolves quickly without clumps, which is good for mixing.

②Provide high bond strength.


9. Extruded cement sheet

①With high cohesiveness and lubricity, it can enhance the processability of extruded products.

②Improve the strength of the green body, promote the hydration and solidification effect and increase the yield.
