Hydroxypropyl Methylcellulose is a non-ionic cellulose ether made through a series of chemical processes, with the natural polymer cellulose as the raw material. It is odorless, tasteless and non-toxic white powder. In cold water, it swells into a clear or slightly turbid colloidal solution. Hydroxypropyl Methylcellulose and Methylcellulose can be used in building materials, coating industry, synthetic resin, ceramic industry, medicine, food, textile, agriculture, daily chemicals and other industries.

Major Applications of Hydroxypropyl Methylcellulose in Building Materials

1. Cement-based Plastering Mortar

1) Improve the homogeneity, enabling plastering mortar easier for trowel coating, while improving the sag resistance, enhancing liquidity and pumpability and improving the working efficiency.

• Increase the water retention, extend the storage time of mortar and improve the working efficiency, beneficial for mortar hydration and solidification to produce high mechanical strength.

3). Control the air entrainment, thus eliminating the cracks on the surface of coatings and forming an ideal smooth surface.

2. Gypsum-based Plastering Mortar and Gypsum Products

1) Improve the homogeneity, enabling plastering mortar easier for trowel coating, while improving the sag resistance, enhancing liquidity and pumpability and improving the working efficiency.

• Increase the water retention, extend the storage time of mortar and improve the working efficiency, beneficial for mortar hydration and solidification to produce high mechanical strength.

3). Control the uniform consistency of mortar and form an ideal surface coating.

3. Masonry Mortar

1). Enhance the adhesion onto the masonry surface, improve the water retention and increase the mortar strength.

• . Improve the lubricity, plasticity and application properties; the mortar improved by the use of cellulose ether is easier for construction, saves the construction time and reduces the construction cost.

• . Cellulose ethers with particularly high water retention apply to highly water-absorbent bricks.

4. Panel Joint Fillers

1). Feature excellent water retention, extend the opening time and improve the working efficiency; act as a high-quality lubricant, easier for mixing.

• . Increase the resistance to shrinkage and cracking; improve the quality of coating surface.

• . Enhance the adhesion of bonding surface; provide with a flat and smooth texture.

5. Ceramic Tile Adhesives

• . Facilitate the dry mixing of ingredients without producing clumps; increase the application speed; improve the application performance; save the working time; and reduce the working cost.

2). Improve the tiling efficiency and provide with excellent adhesion effects by extending the opening time.

6. Self-Leveling Flooring Materials

1). Provide with the viscosity and act as an anti-settling additive.

• . Enhance the liquidity pumping and improve the flooringefficiency.

• . Control the water retention and shrinkage property, and reduce cracking and shrinkage of floor.

7. Water-based Coatings

1). Prevent the solid precipitation and extend the shelf life. Feature high biological stability and excellent compatibility with other components.

2). Improve the liquidity, provide with favorable splash-proof, anti-sag and leveling properties, and ensure excellent surface finish.

8. Wallpaper Powder

1). Dissolve quickly without lumps, conducive to mixing.

• . Provide with high bond strength.

9. Extruded Cement Panels

1). Feature high bonding and lubricity; enhance the processing properties of extruded products.

• . Improve the green strength, promote hydration and solidification effects, and increase the rate of finished products.

10. Dedicated Hydroxypropyl Methylcellulose Products for Ready-mixed Mortar

Dedicated Hydroxypropyl Methylcellulose products for ready-mixed mortar have superior water retention to ordinary products in ready-mixed mortar, ensuring the full hydration of inorganic cementitious materials and significantly preventing the decrease in bond strength caused by drying too fast as well as cracks resulting from drying shrinkage. Hydroxypropyl Methylcellulose also has a certain air-entraining effect. Dedicated Hydroxypropyl Methylcellulose products for ready-mixed mortar has moderate and uniform air entrained, and small bubbles introduced, which could improve the strength and troweling of ready-mixed mortar. Dedicated Hydroxypropyl Methylcellulose products for ready-mixed mortar has a certain set-retarding effect, can extend the opening time of ready-mixed mortar and reduce the difficulty of construction.
