Effect of hydroxypropyl methylcellulose HPMC on cement-based building materials mortar

1. Masonry mortar plastering mortar
High water retention can fully hydrate cement. Significantly increase the bond strength. At the same time, the tensile and shear strength can be appropriately improved. Greatly improve the construction effect and work efficiency.
2. Water resistant putty
The main function of cellulose ether in putty is to retain water, bond and lubricate, so as to avoid cracks or powdering caused by too fast water loss. At the same time, it increases the adhesion of putty, reduces the sagging phenomenon in construction, and makes the construction more smooth and labor-saving.
3. Interface agent
It is mainly used as a thickener, which can improve the tensile strength and shear strength, improve the surface coating, and enhance the adhesion and bonding strength.
4. Exterior wall external insulation mortar
Cellulose ether plays a key role in bonding and increasing the strength in this material, making the mortar easier to coat, improving the work efficiency, and at the same time, it has the ability to resist sagging. The high water retention performance can prolong the working time of the mortar, improve the anti shrinkage and anti cracking properties, improve the surface quality, and improve the bonding strength.

5. Tile adhesive
The high water retention can significantly improve the bonding strength of ceramic tiles and substrates without pre soaking or wetting them. The slurry can have long construction cycle, fine and uniform, convenient construction, and good skid resistance.
6. Joint sealant
The addition of cellulose ether makes it have good edge adhesion, low shrinkage and high wear resistance, which protects the base material from mechanical damage and avoids the negative impact of water infiltration on the whole building.
7. Self leveling material
The stable viscosity of cellulose ether ensures good fluidity and self leveling ability. Controlling the water retention rate enables it to solidify rapidly and reduce cracking and shrinkage.
