Construction grade HPMC & HEMC in building materials
July 26th 2024
Hydroxypropyl methyl cellulose (HPMC) is a non-ionic cellulose ether that is widely used as a thickener, water retention agent, and binder in tile adhesive formulations. It is a versatile additive that improves the workability, adhesion, and durability of tile adhesives.
Benefits of using HPMC in tile adhesive:
Improved workability: HPMC enhances the workability of the adhesive, making it easier to apply and spread evenly. This is particularly important for large tiles or vertical applications.
Extended open time: HPMC helps retain moisture in the adhesive, which prolongs the open time before it starts to set. This allows for more precise adjustments and positioning of tiles.
Enhanced adhesion: HPMC strengthens the bond between the adhesive and the tile, resulting in a stronger and more durable bond.
Reduced slumping and sag: HPMC’s thickening effect minimizes slumping or sagging of the adhesive, ensuring that tiles remain in place even when applied on vertical surfaces.
Improved flexibility: HPMC imparts flexibility to the adhesive, allowing it to accommodate slight movements or expansions without breaking or cracking.
Overall, HPMC is a valuable additive in tile adhesive formulations, offering significant benefits in terms of workability, adhesion, and durability. It is a widely used and trusted additive in the tile adhesive industry.
