The improved adhesion also allows the mortar to withstand external factors such as temperature changes and humidity, further enhancing its performance.
Another benefit of cellulose HPMC in putty powder mortar is its ability to improve the workability and spreadability of the mixture. It reduces the friction between the particles, making the mortar easier to mix and apply. This results in a smoother and more consistent texture, reducing the effort required during application. The improved workability and spreadability also contribute to a more efficient and time-saving construction process.
Lastly, cellulose HPMC is a non-toxic and environmentally friendly additive. It does not release harmful substances into the environment during application or drying. This makes it a safe choice for both workers and the occupants of the building. Additionally, cellulose HPMC is biodegradable, meaning it breaks down naturally over time without causing any harm to the environment.
In conclusion, the application of cellulose HPMC in putty powder mortar offers numerous benefits that enhance its overall quality and performance. Its thickening and water retention properties improve workability and prevent cracking, while its increased adhesion ensures a long-lasting finish. The improved workability and spreadability of the mixture make the construction process more efficient, and its non-toxic and environmentally friendly nature make it a safe choice. With all these advantages, it is no wonder that cellulose HPMC is widely used in the construction industry for putty powder mortar.
