HPMC for Self-Leveling

Application of hpmc in self-leveling mortar

Hydroxypropyl Methylcellulose (HPMC) is commonly used as an additive in self-leveling mortars due to its excellent water retention and thickening properties. Here are some specific applications of HPMC in self-leveling mortars:
  1. Water Retention: HPMC improves the water retention of self-leveling mortars, allowing them to maintain their workability for a longer period. This is particularly important in self-leveling mortars because they require a longer working time to achieve a smooth surface finish.
  2. Thickening: HPMC acts as a thickening agent in self-leveling mortars, giving the mortar the right consistency and viscosity needed for easy application. The thickening properties also help to reduce the settling of heavy aggregates in the mixture, thus enhancing the self-leveling properties of the mortar.
  3. Binding: HPMC improves the binding properties of self-leveling mortars, which enhances the adhesion of the mortar to the substrate. This ensures that the self-leveling mortar remains intact and does not crack or peel off easily.

In summary, HPMC is an important additive in self-leveling mortars as it improves the water retention, thickening, binding, and sag resistance properties of the mortar, making it easier to apply and ensuring a smooth, even surface finish.
