Tiles have been a popular choice for flooring, walls and decorative designs for centuries. From palaces to haciendas and from modern apartments to commercial buildings, tiles have become an integral component for enhancing the aesthetics of any space. However, cement-based tile adhesives being used for installing tiles are not environmentally friendly. To minimize the environmental impact of these adhesives, Hydroxypropyl methylcellulose (HPMC) is a viable solution.
What is HPMC?
HPMC is a cellulose ether that is derived from natural sources such as wood pulp and cotton fibers. It is a water-soluble, biodegradable and non-toxic polymer that has numerous applications in the construction industry such as dry mix mortars, paints, and coatings. HPMC is a popular ingredient in tile cement adhesives due to its excellent water retention, workability, adhesive strength, and flexibility characteristics.
Benefits of using HPMC in tile cement adhesive.
Reduced Environmental Impact.
Traditional cement-based tile adhesives contain Portland cement, which is produced by burning limestone and other materials that release harmful CO2 gases in the atmosphere. In contrast, HPMC-based tile adhesives are environmentally friendly since they do not contain harmful chemicals or leave a negative environmental footprint. HPMC is derived from renewable resources, and its manufacturing process does not produce toxic products or hazardous waste.
Excellent Water Retention Properties.
One of the significant advantages of using HPMC in tile cement adhesives is its exceptional water retention properties. HPMC can absorb and retain large quantities of water, which helps to improve the workability of the mortar and enhance the bond strength between the tiles and the substrate. The superior water retention properties of HPMC help to reduce the chances of water loss, which can lead to shrinkage and cracking of the adhesive.
Improved Workability.
HPMC-based tile adhesive provides improved workability due to its excellent binding properties. The adhesive is easy to mix and apply, and it allows for improved precision in the application process. The workability of the cement adhesive is particularly crucial when installing tiles on a vertical surface, and HPMC helps to ensure the adhesive is applied evenly and consistently over the wall surface.
Exceptional Bond Strength.
The bond strength of HPMC-based tile adhesives is superior to traditional cement-based adhesives. This increased strength is due to the excellent water retention properties of HPMC, which help to maintain the consistency of the adhesive. The improved bond strength of the adhesive facilitates the durability of the installed tiles, and it also helps to minimize the water infiltration under the tiles, which can lead to damage.
How to choose the right HPMC for your tile adhesive.
When it comes to selecting HPMC for your tile cement adhesive, there are several factors you should consider. These include viscosity, surface tension, degree of substitution, and gel point. The right combination of HPMC properties will ultimately depend on the specific needs of your project. The following are some tips on choosing the right HPMC for your tile adhesive:
Viscosity.
The viscosity of HPMC influences the workability and adhesive properties of the tile adhesive. Low viscosity HPMC is suitable for applications where fast setting and low consistency is required. High viscosity HPMC is suitable for applications where greater water retention and workability is required.
Surface Tension.
The surface tension of HPMC indicates the ease of spreadability of the adhesive surface. The lower the surface tension, the greater is the spreadability of the adhesive. HPMC with a low surface tension is recommended for large surface coverage.
Degree of Substitution.
The Degree of Substitution (DS) shows the proportion of the sub-units in the HPMC molecule that have been substituted. The higher the DS, the greater the extent of the modification of the HPMC molecule. This modification influences the water retention and adhesive properties of the HPMC.
Gel Point.
The Gel Point is the temperature at which the HPMC begins to form a gel-like structure. The Gel Point influences the workability and set properties of the adhesive. HPMC with a high Gel Point is recommended for warm weather conditions where faster set times are needed.
Conclusion.
In conclusion, HPMC-based tile cement adhesives are a suitable and environmentally friendly option for minimizing the environmental impact of traditional cement-based adhesives. HPMC offers numerous benefits such as exceptional water retention properties, improved workability, and superior bond strength. By choosing the right HPMC for your tile adhesive, you can optimize the performance of your adhesive for your specific project requirements. Ultimately, HPMC-based tile cement adhesives are a reliable and efficient way to enhance your tile installation while minimizing your environmental footprint.
