Why add hydroxypropyl methyl cellulose in mortar?
May 7th 2024
HPMC powder, also known as hydroxypropyl methylcellulose, is another common additive used in tile adhesive formulations to improve the performance of the adhesive. HPMC powder can be used to improve the adhesion, workability, and water retention of tile adhesive formulations.
HPMC powder works by forming a protective film around the cement particles, improving water retention, and slowing down the drying process of the adhesive. This results in a longer open time, which allows for more time to lay tiles before the adhesive sets. Additionally, the film formed by HPMC powder helps to improve the bond strength between the adhesive and the tile.
When using HPMC powder in tile adhesive formulations, it is important to follow the manufacturer’s instructions carefully to ensure the correct dosage and mixing procedures are used. The amount of HPMC powder required will depend on factors such as the type of tile, the substrate, and the environmental conditions.
Overall, HPMC powder is a valuable additive for improving the performance of tile adhesive formulations, and it can help to ensure a successful tile installation.
