Hydroxypropyl Methyl Cellulose HPMC in Building Materials

Hydroxypropyl methylcellulose HPMC is easily soluble in cold water, and it will be difficult to dissolve in hot water. But its gelation temperature in hot water is significantly higher than that of methyl cellulose. The dissolution in cold water is also greatly improved compared to methyl cellulose.

Hydroxypropyl Methyl Cellulose HPMC

Hydroxypropyl methyl cellulose (HPMC) is a non-ionic cellulose ether made from natural polymer material cellulose through a series of chemical processing. Hydroxypropyl methyl cellulose (HPMC) is an odorless, tasteless, non-toxic white powder that can be dissolved in cold water to form a transparent viscous solution. HPMC has the properties of thickening, bonding, dispersion, emulsification, film formation, suspension, adsorption, gelation, surface activity, moisture retention and protective colloid.

 

 Application of Hydroxypropyl Methyl Cellulose HPMC in Building Materials

1. Masonry mortar and plastering mortar

High water retention can fully hydrate the cement. Significantly increase the bond strength. At the same time, it can appropriately improve the tensile and shear strength. Greatly improve the construction effect and increase work efficiency.

2. Water resistant putty

The main functions of cellulose ether in putty are water retention, adhesion and lubrication, to avoid excessive water loss and cause cracks or powder removal. At the same time, it increases the adhesion of the putty, reduces the sag during construction, and makes the construction smoother. Save effort.

3. Interface agent

Mainly used as a thickener, it can improve the tensile strength and shear strength, improve the surface coating, enhance the adhesion and bonding strength.

4. External thermal insulation mortar

Cellulose ether in this material mainly plays the role of bonding and increasing strength, making the mortar easier to coat, improving work efficiency, and having the ability to resist sag. The higher water retention performance can extend the working time of the mortar and improve the resistance to shrinkage and Crack resistance, improve surface quality, and increase bonding strength.

5. Tile adhesive

High water retention eliminates the need for pre-soaking or wetting the tiles and substrates, and significantly improves the bonding strength. The slurry can be constructed with a long period of time, is delicate, uniform, convenient for construction, and has good slip resistance.

6. Fill in the face

The addition of cellulose ether makes it have good edge adhesion, low shrinkage and high abrasion resistance, protects the base material from mechanical damage, and avoids the negative impact of water penetration on the entire building.

7. Self-leveling material

The stable viscosity of cellulose ether ensures good fluidity and self-leveling ability, and controls the water retention rate to enable rapid solidification and reduce cracking and shrinkage.
