By retaining moisture, HPMC allows the putty to cure properly, resulting in a stronger and more stable surface.
Another advantage of using HPMC in interior wall putty is its resistance to sagging. HPMC imparts thixotropic properties to the putty, which means it becomes less viscous when subjected to shear stress. This prevents the putty from sagging or slumping when applied on vertical surfaces, ensuring a uniform thickness and preventing drips or runs. The resistance to sagging provided by HPMC allows for easier application and reduces the need for rework.
In conclusion, the application of HPMC in interior wall putty offers several benefits. It improves workability, enhances adhesion, retains moisture, and prevents sagging. These properties make HPMC an ideal additive for interior wall putty, ensuring a smooth and durable finish. As the construction industry continues to evolve, the use of HPMC in wall putty formulations is expected to increase, further enhancing the performance and quality of interior wall finishes.
