There are several benefits to using HPMC powder in these construction products. Firstly, it helps to increase the water retention of cement mortar which prevents cracks and improves workability. Secondly, it increases the open time of cement-based products so they can be used longer before they need to be applied or set. Finally, it helps to develop the strength and durability of cement mortar by holding onto moisture and ensuring a better bond with other materials such as bricks or tiles. Additionally, HPMC can also help reduce shrinkage while improving the cohesion and adhesion of cement-based products.
