Application of Cellulose HP in Special Mortars
Applied to self-leveling mortar
The effects that can be achieved by using low-viscosity HP cellulose ether in self-leveling mortar are:
Ensure the flowability of self-leveling mortar.
Enhancing the Self-Healing Capability of Self-Leveling Mortar
Helps to form a smooth surface.
Reduce shrinkage and increase load-bearing capacity
Enhance the bond strength and cohesion of self-leveling mortar to the substrate.
Applied to tile adhesive
As a functional decorative material, ceramic tiles have been widely used around the world, and ensuring their secure and durable installation has long been a key concern. The development of tile adhesives has, to a certain extent, enhanced the reliability of tile installation. Different construction practices and methods impose varying performance requirements on tile adhesives. In current domestic tile-installation projects, the thick-bed method—traditionally involving back-coating with adhesive—remains the dominant technique. Under this approach, tile adhesives are expected to exhibit easy mixing; good spreadability without sticking to the trowel; strong initial tack; and excellent resistance to slippage. With advances in tile-adhesive technology and improvements in application techniques, the thin-bed method using a notched trowel is also gaining traction. This method places greater demands on tile adhesives: easy mixing; superior spreadability without sticking to the trowel; robust anti-slip performance; good wetting of the tile surface; and an extended open time. In most cases, selecting appropriate grades of cellulose ethers can help achieve the desired workability and ease of application for tile adhesives.
