Characteristics of hpmc for gypsum mortar

Characteristics of hpmc for gypsum Mortar:

1. Excellent Construction Performance:
   • Easy and smooth application during plastering, allowing for one-time shaping.
   • Exhibits plasticity, contributing to a more flexible application process.
2. Strong Compatibility:
   • Compatible with various types of gypsum bases.
   • Reduces gypsum setting time and minimizes drying shrinkage.
   • Helps prevent issues such as surface hollowing and cracking.
3. Effective Water Retention:
   • Prolongs the workable time of gypsum mortar.
   • Improves the thickness resistance of gypsum mortar.
   • Enhances the bonding strength between gypsum mortar and the substrate.
   • Demonstrates good wet adhesion performance, reducing problems like dusting.
4. Increased Gypsum Coverage Rate:
   • Compared to similar Hydroxypropyl Methyl Cellulose ethers, it significantly increases the coverage rate.
   • Substantially improves the application area per unit, reducing labor intensity.
   • Saves materials and enhances economic efficiency.
5. Excellent Anti-Sagging Performance:
   • During thick layer plastering, single-pass construction does not result in sagging.
   • For multiple passes exceeding 3cm, sagging does not occur during plastering, demonstrating good plasticity.
6. Application Areas and Recommended Dosage:
   • Recommended for lightweight base coat plastering gypsum.
   • Suggested dosage: 2.5-3.5 kg per ton.
