Additives have become a common part of tile adhesives and play an important role in their performance and effectiveness. The use of additives in tile adhesives is critical in today’s construction industry. Additives help enhance adhesive properties such as water retention, processability and bond strength, making them more sustainable and functional. HPMC (Hydroxypropyl Methyl Cellulose) is an example of an additive commonly used in the tile adhesive industry. This article outlines the benefits of using HPMC in tile adhesive manufacturing.
What are HPMCs?
Hydroxypropyl methylcellulose is a derivative of cellulose and forms a white or light yellow powder. It is non-toxic, odorless and has excellent water solubility. HPMC is obtained by the hydrolysis of plant fibers to produce cellulose, which is then chemically modified by adding methoxy and hydroxypropyl groups to the ether linkages. It is soluble in water, ethanol and acetone and has some properties of organic and inorganic compounds. It is widely used in industries such as construction, cosmetics, food, pharmaceuticals and coatings.
Benefits of Using HPMC in Tile Adhesives
1. Improve water retention
One of the main benefits of using HPMC in tile adhesives is that it improves water retention. Water retention is critical in the adhesive manufacturing process as it ensures that the adhesive remains workable and does not dry out too quickly. When HPMC is added to an adhesive, it combines with water molecules to form a gel-like consistency. The gel nature of HPMC ensures that the adhesive mixture remains wet and cohesive, which improves adhesive processability and enhances tile bonding.
2. Improve workability
The use of HPMC in tile adhesives improves workability, which is how easily the adhesive is mixed, applied and adjusted. Machinability is critical in the manufacturing process as it determines the efficiency of the installation process. When HPMC is added to adhesives, it acts as a thickener, resulting in a better consistency and easier handling. The improved consistency of the adhesive ensures that it remains cohesive and can be easily shaped, molded or spread to level surfaces to create a smooth surface.
3. Increase bond strength
Bond strength is determined by the bond between the substrate (tile) and the adhesive. Using HPMC in tile adhesives increases bond strength by increasing the bond between the tile and the adhesive. The role of HPMC is to increase the contact area between the substrate and the adhesive. This enhanced contact results in a stronger bond that can withstand greater pressure and weight. The strong adhesion provided by HPMC ensures that tiles stay in place even in high traffic areas and remain resistant to mechanical forces.
4. Reduce shrinkage
As the adhesive dries, it shrinks, creating gaps and spaces between the tiles. Gaps and spaces can appear unsightly and also allow moisture to penetrate, which can cause the tiles to peel off. Using HPMC in tile adhesives ensures that the adhesive dries slowly and evenly, reducing shrinkage. The slow drying process allows the adhesive to settle, ensuring that each tile lays evenly, minimizing the risk of gaps due to shrinkage.
5. Improve weather resistance
The use of HPMC in tile adhesives can improve the weatherability of the adhesive. HPMC provides an extra layer of protection, ensuring the adhesive remains intact even in harsh weather conditions. External conditions such as temperature fluctuations, humidity and rain can weaken the adhesive’s bond and reduce its effectiveness. HPMC provides a protective coating that protects the adhesive from harsh weather conditions, ensuring it remains effective over a longer period of time.
in conclusion
Adding HPMC to tile adhesives offers significant advantages, enhancing the adhesive’s effectiveness, functionality, sustainability and strength. Benefits include improved water retention, enhanced processability, increased bond strength, reduced shrinkage and improved weatherability. These benefits can enhance the quality of building works that remain intact and functional even in adverse weather conditions. Due to its many advantages, the use of HPMC in tile adhesives has become a common aspect of the tile adhesive manufacturing industry. Its versatility has made it popular and the first choice of construction professionals worldwide
