1. Water retention
Preventing excessive water loss: HPMC can significantly improve the water retention of tile adhesives and prolong the cement hydration reaction time, especially in
high temperature or dry environments, to prevent the adhesive from cracking or decreasing the bonding strength due to excessive water loss
Improving cement hydration efficiency: The water retention effect ensures that the cement is fully hydrated, thereby improving the final strength and durability of the adhesive.
2. Thickening and construction performance
Adjusting viscosity: HPMC can increase the viscosity of the adhesive, improve the anti-sagging property, and make the adhesive easier to apply, especially for vertical walls or large-sized tiles.
Extending open time: By adjusting the amount of HPMC added, the open time of the tile adhesive (i.e., the time the adhesive can still maintain its bonding performance after construction) can be extended, making it easier to adjust the position of the tiles.
3. Anti-slip property
When pasting large-sized or low-water-absorption tiles (such as vitrified tiles and marble), HPMC can effectively reduce the sliding phenomenon of tiles before curing (anti-slip property) and improve construction efficiency.
4. Improved bonding strength
HPMC optimizes the cohesion and flexibility of the adhesive, enhances the bonding strength with tiles and substrates, and reduces the risk of hollowing and falling off.
5. Anti-cracking and durability
By improving the flexibility of the adhesive, HPMC can reduce stress cracks caused by thermal expansion and contraction or vibration of the substrate and improve long-term durability.
Summary
HPMC significantly optimizes the construction performance and final bonding effect in tile adhesives through water retention, thickening, anti-slip and other effects, and is one of the key additives to improve the comprehensive performance of tile adhesives.
