Cement Based Tile Adhesive Mortars Additives Redispersible Polymer Powder Vae/RdpMay 26th 2023
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.
How Does HPMC Work?
HPMC works by binding with water molecules and increasing their viscosity which then helps improve the flowability and workability of cement mortars. This means that you don’t need to use as much water when preparing cement mortars since HPMC will help hold onto this moisture for longer periods of time. Furthermore, because HPMC holds onto moisture for longer periods of time it can also help reduce shrinkage in some cases where this is an issue for certain projects.
