What is HPMC in DryMix Mortar?
Definition of Dry-Mix Mortar
Dry-mix mortar is a pre-blended mixture of cement, sand, and functional additives that only requires water at the job site. It is widely used in construction for plastering, bricklaying, tile fixing, and finishing applications.
Role of HPMC in Mortar
HPMC (Hydroxypropyl Methyl Cellulose), also called cellulose ether, is a vital additive in mortar. Keyong HPMC controls the water retention, consistency, and workability of mortar, ensuring longer open time, better adhesion, and smooth construction performance.
the types of HPMC for Drymix Mortar
U5040 – Versatile Cement Mortar Additive
U5040 is designed as a moderate-viscosity mortar additive, balancing ease of mixing with efficient finishing. It maintains good water retention to ensure uniform setting and curing, helping prevent uneven surfaces or premature drying. U5040 supports high filler tolerance, making it suitable for cost-effective formulations without compromising performance. This additive is ideal for general bonding and plastering applications, delivering consistent results in everyday construction work.
Key Benefits:
- Moderate viscosity for easy mixing and finishing
- Maintains water retention for uniform setting
- High filler tolerance for economical formulations
- Suitable for general bonding and plaster applications
U5070 – High-Performance Bonding and Durability Enhancer
U5070 is engineered for mortars that require strong water retention even at low dosage, making it highly efficient and cost-effective. It significantly improves mortar plasticity and pumpability, facilitating smooth application in both manual and machine-applied processes. U5070 enhances bond strength and long-term durability, ensuring a robust and reliable construction. Additionally, it helps control sagging and promotes smooth surface leveling, making it ideal for high-quality structural and decorative mortars.
Key Benefits:
- Excellent water retention at low dosage
- Enhances mortar plasticity and pumpability
- Improves bond strength and long-term durability
- Controls sagging and supports smooth surface leveling
Performance Benefits of Keyong HPMC in Mortar
HPMC for Drymix Mortar
Excellent Water Retention
Keyong HPMC provides outstanding water retention capacity, ensuring that the mortar does not lose moisture too quickly. This is critical for:
- Complete cement hydration → improves mortar strength and bonding.
- Consistent curing → prevents premature drying, especially in hot or windy environments.
- Better adhesion and durability → ensures tiles and coatings stay firmly attached.

Improved Workability
The addition of Keyong HPMC significantly improves the plasticity and smoothness of mortar:
- Makes mortar easier to mix with uniform consistency.
- Enhances spreadability during troweling or plastering.
- Reduces drag and stickiness, lowering the effort required by workers.
HPMC for Drymix Mortar
Extended Open Time
Open time refers to how long mortar remains usable after application. With Keyong HPMC:
- Mortar retains workability for a longer period.
- Contractors have more flexibility in adjusting or repositioning tiles.
- Reduces material waste caused by early setting.
