Top 4 Tips About HPMC Solubility
December 18th 2024
The primary function of HPMC in tile adhesives is water-retaining and thickening. The purpose is to increase the final solidification strength of the tile adhesive, extend the open time, and improve its workability. Usually, when we evaluate the performance of tile adhesive, in addition to its workability and anti-sliding ability, we also pay attention to its open time. For example, in a wet mortar, the water in the mortar will evaporate, and then cellulose ether will be gathered on the surface. A film will form on the mortar surface within 5 minutes, which will reduce the subsequent evaporation rate. Therefore, hydroxypropyl methyl cellulose (HPMC) can extend the opening hours.
