HPMC

Application areas

The main roles of HPMC (Hydroxypropyl Methyl Cellulose) in dry-mix mortar are as follows:
- Water Retention & Thickening: Reduces water loss, extends open time, ensures sufficient hydration of cement, and improves strength and durability.
- Workability Improvement: Increases mortar plasticity and lubricity, reduces operational resistance, and enables smoother and more uniform application.
- Bond Strength Enhancement: Enhances adhesion between mortar and substrates (such as bricks, concrete) through colloidal adsorption, minimizing hollowing.
- Anti-Cracking: Improves mortar flexibility, inhibits cracks caused by drying shrinkage, and enhances deformation resistance.
- Thixotropy & Homogeneity Maintenance: Imparts thixotropy, prevents aggregate sedimentation and segregation, and ensures mortar uniformity and stability.
