- Conclusion
- 4. Film-Forming Property HPMC can form a thin, flexible film when hydrated, which makes it ideal for use as a coating or binder.
- In the construction industry, HPMC powder is used as a water-retaining agent, thickener, and binder in cement-based materials
- Another important property of HPMC is its ability to form films. When applied to surfaces, it dries to form a thin, transparent layer that provides protection and prevents moisture loss. This makes it an excellent choice for use in the food industry, where it can be used to coat fruits and vegetables to extend their shelf life. In the pharmaceutical industry, HPMC is used to manufacture capsules and tablets, where it helps to control the release of active ingredients.
- One of the key functions of mortar bonding agents is to improve the bond strength between the mortar and the substrate. This is particularly important in applications where the substrate is not perfectly clean or smooth, as the bonding agent helps to fill in any gaps or imperfections, creating a strong and reliable bond. Without a bonding agent, the mortar may not adhere properly to the substrate, leading to potential failure and structural issues down the line.
