Hydroxypropyl Methylcellulose(HPMC)
CAS:9004-65-3
Hydroxypropyl methylcellulose is one of the key components of dry-mix mortar as it can affect the key properties of dry-mix mortar workability, water retention, rheology and thixotropy.

| HPMC-320 | 160000~220000CPS | Gypsum-based products |
1.Water Retention
The excellent water retention of hydroxypropyl methylcellulose makes the cement have a longer hydration time and improves the adhesion between the mortar and the substrate. Effectively prevent the mortar from drying and cracking caused by excessive water loss, so that the mortar has a longer construction life.
2.Construction Improvement
The thickening effect of hydroxypropyl methylcellulose can control the mortar to achieve the best consistency, improve the cohesive force of the mortar, achieve anti-drip effect, improve operability, and greatly improve construction efficiency. The consistency and slip resistance of the mortar is a very important requirement. For thick building and tile adhesives, the mortar needs to be of proper consistency and slip resistance.
3.Improve the Bond Strength of the Mortar
Hydroxypropyl Methylcellulose can improve the bonding strength of mortar, even in high temperature environment, it can ensure sufficient moisture of mortar, and make cement fully hydrated, thus ensuring better bonding performance of the mortar and ensuring mortar to various substrates. All have a good bonding effect.
4.Air entraining agent
In the mortar, due to the addition of hydroxypropyl methylcellulose, a certain amount of tiny, uniform and stable air bubbles are introduced into the fresh mortar. Due to the ball effect, the mortar has good workability, reduces the shrinkage and cracking of the mortar, and improves the yield of the mortar.
