This results in a finished surface that is resistant to cracking and crumbling, ensuring a high-quality and long-lasting repair.
Lastly, HPMC is also known for its excellent resistance to sagging. When applied to vertical surfaces, putty needs to stay in place and not slide or sag. HPMC helps to prevent sagging by providing a thixotropic effect, meaning that the viscosity of the putty decreases under shear stress. This allows the putty to flow easily during application but then quickly regain its viscosity, preventing sagging and ensuring a smooth and even finish.
In conclusion, the addition of HPMC to putty powder offers several benefits that improve its workability, adhesion, water retention, strength, and resistance to sagging. This versatile compound enhances the overall performance of putty powder, making it easier to work with and ensuring a high-quality and long-lasting repair. So, the next time you come across HPMC in the list of ingredients for putty powder, you can rest assured that it is there to enhance its performance and provide you with a smooth and durable finish.
