HPMC in Polymer Modified Thinset Mortar: The Ultimate Guide to Enhanced Tile Adhesion (EN 12004 Certified)

Material Properties:

• CAS No.: 9004-65-3
• Solubility: Cold water dispersible
• Viscosity: 40,000-200,000 mPa·

4 Key Performance Enhancements:

Water Retention

• HPMC can absorb and retain plenty of water. Enough water results in longer open time instead of premature drying during tile installation. Enough water is also an essential requirement for a complete hydration process to promote bonding strength.
  • Maintains 98% hydration efficiency
  • 90-minute adjustable setting time
  • Prevents premature drying (EN 1348 compliant)

Anti-Slip Bonding

• HPMC enhances the cohesion and adhesive properties of the thinset mortar. So the tiles, especially large-format ones applied on vertical surfaces, will not slip down due to gravity and displacement.
  • Vertical surface adhesion up to 2.5 N/mm²

Microstructure Optimization

• HPMC molecules form a thin film between the mortar and the tile, strengthening the adhesive bond between the two. One key benefit of this is to minimize issues such as hollowing and detachment.
  • Reduces porosity by 60%

Thickening Effect

• HPMC molecules dissolved in water can form polymer chains. These chains establish a three-dimensional network structure, significantly increasing the thin-set mortar’s viscosity and improving its workability.
