Why is it important to add hpmc to tile adhesive?
Hydroxypropyl Methyl Cellulose (HPMC) is a commonly used additive in tile adhesives for several important reasons. Adding HPMC to tile adhesive formulations provides various benefits that enhance the performance and application of the adhesive in the context of tile installation. Here are some of the key reasons why HPMC is important in tile adhesive : Improved Workability: HPMC acts as a thickening and water-retention agent. It increases the workability of the tile adhesive, making it easier to mix and apply. The adhesive becomes more cohesive and can be spread smoothly and evenly onto the substrate. Water Retention: HPMC helps the adhesive retain water, preventing premature drying and ensuring a longer open time. This extended open time allows installers to work with the adhesive for a longer period before it sets, which is particularly beneficial when working with larger or more intricate tile installations. Reduced Shrinkage: HPMC helps reduce the risk of shrinkage cracks in
