This binding effect ensures that the putty paste adheres well to the surface it is applied to, preventing it from cracking or peeling off over time.

Furthermore, HPMC acts as a film-former. As the putty paste dries, the HPMC forms a thin film on the surface. This film acts as a protective barrier, preventing moisture from seeping into the putty and causing it to deteriorate. This is particularly important in areas where water exposure is common, such as bathrooms and kitchens.

In addition to its binding and film-forming properties, HPMC also enhances the workability of putty powder. It improves the spreadability and smoothness of the paste, making it easier to apply and work with. This is especially beneficial for professionals who need to achieve a flawless finish in their projects.

Moreover, HPMC contributes to the overall strength of the putty. It improves the cohesion and adhesion of the particles, making the putty more resistant to cracking and crumbling. This is crucial in ensuring the longevity of the applied putty, as it needs to withstand the stresses and strains that may occur over time.

Lastly, HPMC helps to control the drying time of the putty. By adjusting the concentration of HPMC in the formulation, manufacturers can modify the setting time of the putty paste. This allows for greater flexibility in application, as it can be tailored to suit different project requirements.

In conclusion, the main function of the application of HPMC in putty powder is to enhance its durability and water resistance. HPMC acts as a binder, film-former, and water retention agent, contributing to the overall strength and longevity of the putty.
