The specific role of building grade hydroxypropyl methyl cellulose ether (HPMC)
1. Construction mortar plastering mortar
High water retention can make the cement fully hydrated, significantly increase the bond strength. And at the same time increase the tensile strength and shear strength, greatly improve the construction effect and improve work efficiency.
2.water resistant putty
In the putty, HPMC mainly plays the role of water retention, bonding and lubrication. To avoiding the cracking and dehydration caused by excessive water loss, enhancing the adhesion of the putty and reducing the sag during construction. The phenomenon makes the construction smoother.
3. Stucco plaster series
Among the gypsum series products, HPMC ether mainly plays the role of retaining water, increasing lubrication, and has a certain retarding effect. It solves the problem of drum cracking and initial strength during construction, which can be extended operating hours.
4. Interface agent
It is mainly used as a thickener to improve tensile strength and shear strength. Which improve surface coating, enhance adhesion and bond strength.
5. External wall thermal insulation mortar
HPMC ether plays a role in bonding and increasing strength in this material. Which makes the mortar easier to coat, improves work efficiency, and has more anti-sagging effect. Higher water retention performance can prolong mortar. Working time, improve shrinkage resistance and crack resistance, improve surface quality and improve bond strength.
6. Tile adhesive
The higher water retention capacity does not require pre-soaking or wetting the tiles and the base, and significantly improves the bonding strength. The slurry can be constructed in a long, delicate, uniform, convenient construction, and has good resistance to runtability.
7. Grouting agent and grouting agent
The addition of HPMC ether provides good edge adhesion, low shrinkage and high abrasion resistance, protecting the substrate material from mechanical damage and avoiding the effects of penetration on the entire building.
