Tile adhesives are widely used to install tiles on various surfaces such as walls and floors. They are essential to ensure a strong bond between tile and substrate to avoid potential damage, and to ensure that the installation can withstand various environmental stresses such as humidity, temperature changes and regular cleaning.
One of the ingredients commonly used in tile adhesives is hydroxypropylmethylcellulose (HPMC), a polymer usually derived from cellulose. It is known for its excellent ability to retain water, which makes it an ideal ingredient in tile adhesive formulations.
There are several advantages to using HPMC in tile adhesive formulations. These include;
1. Improve workability
HPMC acts as a rheology modifier in cementitious formulations such as tile adhesives, which means it can significantly improve the workability of tile adhesives. It also reduces the appearance of lumps and clots, which enhances the consistency of the mixture, making it easier for installers to work with.
2. Water retention
One of the advantages of HPMC in tile adhesives is its excellent water retention capacity. It ensures that the adhesive remains usable for a longer period of time and helps the tile adhesive to set. This feature also reduces the risk of shrinkage cracks, which are often caused by loss of water during setting.
3. Increased strength
Another benefit of using HPMC in tile adhesives is that it helps increase the strength of the mix. The addition of HPMC helps stabilize the mixture, adding strength and improving the overall durability of the tile adhesive.
4. Save time
Tile adhesives containing HPMC require less installer mixing and application time due to improved rheology. In addition, the longer working times offered by HPMC mean that larger areas can be covered, resulting in faster tile installations.
5. Reduce environmental impact
HPMC is a natural and biodegradable product. Therefore, the use of HPMC in tile adhesives can reduce the adhesive’s environmental impact and meet the growing demand for environmentally friendly building materials.
In summary, HPMC is an essential component in the production of high-quality tile adhesives. Its water-retention capacity and rheological improvements provide benefits including improved processability, increased strength, reduced environmental impact and time savings. Therefore, some tile adhesive manufacturers have implemented the use of HPMC to improve tile bond strength and increase the durability of their adhesives.
