Hydroxypropyl methyl cellulose in dry mortar, the addition of cellulose ether is very low, but it can significantly improve the performance of wet mortar, which is a major additive affecting the construction performance of mortar. Nowadays, the main cellulose ether used in hydroxypropyl methyl cellulose in dry mortar is hydroxypropyl methyl cellulose ether (HPMC). Hydroxypropyl methyl cellulose in dry mortar HPMC mainly plays the role of water retention, thickening and improving construction performance.

1. Water-resistant putty

Hydroxypropyl methylcellulose cellulose ether in putty mainly plays the role of water retention, bonding and lubrication to avoid cracks and dehydration caused by excessive water loss, and also enhances the adhesion of the putty, reduces the phenomenon of hanging in construction and makes the construction smoother.

2. Construction mortar plastering mortar 

High water retention can make the cement fully hydrated, significantly increase the bonding strength, as well as improve the tensile strength and shear strength, greatly improving the construction effect and work efficiency.

3. Interface agent

Mainly used as thickening agent, it can improve tensile strength and shear strength, improve surface coating, enhance adhesion and bonding strength.

4. Plaster series

Among the gypsum series products, hydroxypropyl methyl cellulose cellulose ether mainly plays the role of water retention and lubrication, and has a certain slow-setting effect, which solves the problems of drum cracking and initial strength failure during construction and can extend the working time.

5. tile bonding agent

Higher water retention can not have to pre-soak or wet tile and base, significantly improve its bond strength, the slurry can be long construction cycle, delicate, uniform, easy to construct, while having good resistance to wetting shift.

6. External wall insulation mortar

Hydroxypropyl methyl cellulose in this material focuses on the role of bonding and increasing strength, making the mortar easier to coat, improve efficiency, while more anti-drape effect, higher water retention properties can extend the working time of the mortar, improve shrinkage resistance and anti-cracking, improve the surface quality, improve bonding strength.

7. Self-leveling materials

The stable bonding of hydroxypropyl methyl cellulose cellulose ether ensures good fluidity and self-leveling ability, and the control of water retention enables it to solidify quickly and reduce cracking and shrinkage.

8. Caulking agent, jointing agent

The addition of hydroxypropyl methyl cellulose cellulose ether makes it have good edge bonding, low shrinkage and high abrasion resistance, which protects the base material from mechanical damage and avoids the impact of infiltration to the whole building.

9. Honeycomb ceramics

In the new cellular ceramics to give the blank lubricity, water retention and improve the strength.

10. Emulsion Paint Coating

In the coating industry hydroxypropyl methyl cellulose cellulose ether can be used as a film-forming agent, thickener, emulsifier and stabilizer, so that it has good abrasion resistance, uniformity, adhesion, improve the surface tension of the PH characterization, and organic solvent mixing effect is also better, high water retention properties make it have good brushability and leveling.
