Key Benefits of HPMC and MHEC in Tile Adhesive

Cellulose ethers form a water-retaining film, reducing water evaporation and ensuring that the tile adhesive remains sufficiently moist during the construction process, preventing the substrate from absorbing excessive water or drying out too quickly on the surface. Their thickening effect can adjust the mortar viscosity, improve the operational smoothness and anti-slip performance, and prevent sticking of the blade or flow during construction. The water-retaining property of cellulose ethers helps the tile adhesive better moisten the substrate, enhancing the bonding effect. By delaying the hydration process, it extends the operability time of the tile adhesive, meeting the construction requirements such as thin-laying methods.

• •Water retention effectCellulose ethers can effectively prolong the opening time of the mortar, preventing excessive evaporation of moisture and avoiding the failure of adhesion or delamination of tiles due to rapid water loss.
• •Thickening and lubricationBy forming a three-dimensional molecular network, cellulose ethers increase the viscosity of the mortar, improve the operability during construction, reduce the phenomenon of run-off, and make it easier to adjust the position of the tiles.
• •Crack Resistance and FlexibilityThe addition of anti-cracking and flexibility cellulose ethers can enhance the flexibility of the mortar, alleviate the stress caused by temperature differences or shrinkage between the tiles and the base, and reduce the risk of cracking.
• •Applicable sceneEspecially when working on substrates with high temperature or high water absorption, the water retention effect of cellulose ethers becomes even more crucial, significantly enhancing the bonding strength and durability of tile adhesives.
