Construction grade HPMC hydroxypropyl methylcellulose Advantages
December 23rd 2024
You’re right, construction grade HPMC is a key ingredient in both tile adhesive and putty. It acts like a multi-tasking superhero, enhancing several properties crucial for these materials. Here’s how HPMC benefits tile adhesive and putty:
Water Retention: Just like in dry mix mortar, HPMC in tile adhesive and putty excels at keeping water from evaporating too quickly. This is especially important to ensure proper curing and prevent cracks.
Workability and Smooth Application: HPMC modifies the consistency of the adhesive or putty, making it more workable and easier to spread. This translates to smoother application and better finishing for professionals.
Extended Open Time: Similar to dry mortar, HPMC extends the open time of tile adhesive and putty. This gives workers more time to adjust and manipulate the material before it sets, reducing the risk of mistakes and wasted product.
Improved Adhesion: By enhancing the overall workability and consistency, HPMC promotes better contact between the adhesive/putty and the tile or substrate. This leads to stronger bonds and a more durable finished product.
Reduced Slip and Sag: HPMC’s thickening properties help prevent the tile adhesive or putty from sagging or slipping, especially important for vertical applications like walls.
Improved Freeze-Thaw Resistance: In some cases, HPMC can introduce tiny air bubbles into the mix. These air voids can improve the freeze-thaw resistance of the adhesive or putty, making them suitable for wider temperature variations.
