HPMC Improves Performance of Tile Adhesives

May. 06, 2024

Tile adhesives are the unsung heroes of construction, ensuring that tiles remain firmly in place over time. One game-changing additive in this sector is Hydroxypropyl Methyl Cellulose (HPMC). By improving the adhesive's performance, HPMC ensures stronger, longer-lasting bonds. Let's dive into how HPMC achieves this and why it's essential for modern construction projects.

Understanding HPMC

Hydroxypropyl Methyl Cellulose (HPMC) is a cellulose ether derivative that acts as a crucial additive in tile adhesives. It contributes to water retention, improves workability, and enhances bonding strength in adhesives. Known for its thickening and stabilizing properties, HPMC is key to ensuring that tile adhesives perform as expected in various conditions.

Benefits of HPMC in Tile Adhesives

Enhanced Water Retention

One of the primary benefits of HPMC is its ability to retain water within the adhesive mixture. This ensures that the adhesive remains workable for longer periods, preventing premature drying and making it easier to adjust tiles during installation.

Improved Bond Strength

HPMC significantly increases the bond strength of tile adhesives. This ensures that tiles remain securely attached to surfaces, reducing the risk of tiles falling off over time. This enhanced bonding is particularly crucial in areas with high foot traffic or where tiles are exposed to varying environmental conditions.

Better Workability

The inclusion of HPMC in tile adhesives improves the overall workability of the mix. It ensures a smoother, more homogenous mixture, making it easier to spread and apply. This leads to a more efficient installation process and a more consistent finish.

Practical Application and Mixing

When preparing tile adhesive with HPMC, it is essential to follow the correct preparation processes to achieve the best results. Here's a quick overview of the steps involved:

Preparation before mixing

First of all, we have to prepare the raw materials for tile adhesive. If you’re scratching your head about the proportions of HPMC and other chemicals to add, don’t worry. You are welcome to seek advice from Kemox’s staff, which can eliminate any confusion you may have in tile adhesives. In a clean mixing bucket, we gradually add the raw materials of the tile adhesive, including HPMC. HPMC is not an ordinary additive, but a secret to improve the performance of the adhesive. We slowly mix the HPMC with the other required chemicals, adhering to the specified proportions. It’s like baking a cake – each ingredient needs to be perfectly balanced for a delicious result.

The Art of Mixing

Next, we gradually add water according to the recommended proportions. It’s like adding water gradually to flour. We use a mechanical mixer to blend the mixture until it becomes smooth, making sure that no lumps appear. This step is crucial because it ensures that the various additives are evenly distributed throughout the binder.

Testing the Tile Adhesive

We used a trowel to scrape out a small piece of tile adhesive for a closer look. The adhesive was then tested by pressing it onto a tile with the trowel and found that the tile was easily pried up. A thin, even layer of adhesive was applied from the tile substrate, slowly with the trowel. It’s like painting on a canvas, but instead of paint, we use adhesive. We press a brick firmly onto the tile on which we have just applied the adhesive.
Wait a few moments and let the adhesive slowly take effect. We want the adhesive to be set in the recommended time frame. After the setting period, it’s time for the moment of truth. We try to check the bond strength by prying the tiles up from the substrate. Since the bond of HPMC is so strong, it feels like the brick and tile have fused together.

Test Results

Our test results show that HPMC is more than just an additive, it’s a tile adhesive’s best friend. It improves the performance of adhesives and makes tiles stick stronger, longer, and more reliably. Therefore, the next time you lay tiles, it is recommended that you add a fixed percentage of HPMC in advance to ensure that your tiles stay where you want them to be no matter what.

HPMC for Tile Adhesive

Product Description

HPMC for Tile Adhesive

HPMC for tile adhesive contains other additives such as cement, sand and limestone, which can increase the adhesion of tile ceramics. Tile adhesive is a new modern decorative material used to paste tiles, face tiles, floor tiles and other decorative materials. There are many kinds of additives in tile adhesive, but usually cellulose ether additives are added to tile adhesive to improve water retention, thickening effect and open time.

Before using HPMC tile adhesive with adhesive will be powder and water 1 : 0.25-0.3 ratio. Stir it to be ready for construction after the adhesive is completely dry, you can adjust the tile position within the allowed operation time (about 24 hours to fill, 24 hours should prevent heavy objects from pressing on the tile surface).

Construction grade hydroxypropyl methyl cellulose is widely used in building grade. For example, tile bonding, tile mortar.

Hydroxypropyl Methyl Cellulose for Tile Adhesive Advantages

HPMC cellulose has many characteristics, such as thickening, water retention, dispersion, emulsification, film formation, adhesion, gelation and adsorption. The HPMC has good effect in tile adhesive, It can be improved the Anti-Slip, water retention, opening time, viscosity and strength of tile adhesion. Due to its high water performance, hydroxypropyl methyl cellulose does not need to be pre-soaked or wetted with tiles and substrates, which can significantly improve the bonding strength. The slurry can be constructed in a longer period, and the construction is convenient and uniform. It is delicate and has good anti-slip performance. HPMC with a thickening, binding, dispersing, emulsifying, PH value of stability, film, suspension, adsorption, gel, surface activity, maintain a features such as water and protective colloid.

1. Enhance water retention characteristics and extend working time.

2. Improve the bonding strength of tile adhesives.

3. Improves flexibility and deformability of the caulk.

4. It can enhance the sag resistance of tile adhesives.

5. Good bond strength, both thick and thin, with reduced shrinkage and tiles that do not crack or fall under stress.

6. Mortar has better malleability and flexibility, which makes construction easier and work more efficient.
