HEMC for Tile Adhesives

Tenessy HPMC for Tile Adhesives
TENESSY™ Hydroxyethyl Methyl Cellulose (HEMC) is a high-performance cellulose ether designed to enhance the consistency, adhesion, and water retention of tile adhesives. It easily dissolves in cold water to form a smooth, thick solution with stable viscosity and excellent flowability.
In tile adhesive formulations, HEMC acts as a key additive that improves the workability, bonding strength, and open time of cement-based systems. Compared to conventional Hydroxypropyl Methyl Cellulose (HPMC), TENESSY™ HEMC provides superior water retention, viscosity stability, and anti-mold performance, making it particularly suitable for applications in hot and humid environments.
How Does HEMC Work in Tile Adhesives
When added to tile adhesives, HEMC creates a protective colloid film around cement particles, effectively controlling the release of water during hydration. This mechanism ensures that the adhesive maintains proper moisture balance, allowing for better cement hydration and stronger bonding between tile and substrate.
At the same time, HEMC increases the viscosity and cohesiveness of the mortar, preventing tile slippage on vertical surfaces. It also extends the open time—meaning workers have more time to adjust and align tiles without losing adhesion—leading to greater efficiency and reduced waste on construction sites.
Recommended HEMC Grades for Tile Adhesives
TENESSY™ provides several grades of HEMC tailored for different types of tile adhesives and construction environments:
HEMC MET40
15,000-25,000 mPa·s
For basic interior wall tile adhesives
HEMC MET60
25,000-35,000 mPa·s For medium-grade wall and floor adhesives
HEMC MET200
≥75,000 mPa·s
For premium-grade tile adhesives needing maximum retention and strength
Key Benefits of Using HEMC in Tile Adhesives
- Excellent Water Retention: HEMC keeps water in the mix longer, ensuring full cement hydration and reducing weak bonding or tile popping.
- Enhanced Workability and Smooth Application: Provides a creamy, non-sticky texture for easy, uniform troweling and smoother construction.
- Strong Anti-Slip Performance: Optimized viscosity keeps tiles firmly in place, even on vertical surfaces.
- Extended Open and Adjustment Time: Gives workers more time to accurately position tiles without losing adhesion strength.
- Consistent Viscosity under Different Conditions: Maintains stable performance under varying temperature and humidity for reliable job-site results.
- Improved Anti-Mold and Storage Stability: Resists microbial growth, extending shelf life and maintaining stability in dry-mix mortars.
Other Cellulose Ether Applications
Tennessee Hydroxypropyl Methylcellulose (HPMC) improves the workability, water retention, and bonding strength of various building materials, delivering reliable performance in self leveling, wall putties, gypsum plaster, exterior insulation and finish systems (EIFS), and other dry-mix products.
