In addition to its superior adhesion properties, VAE redispersible powder offers excellent flexibility. The polymers create a matrix that can accommodate the natural movements in structures due to temperature changes, moisture variations, or settlement. This flexibility translates to lowered risks of structural failures and enhanced longevity of the building materials.

At low concentrations, HEC solutions exhibit Newtonian behavior, where the viscosity remains constant regardless of the shear rate applied. However, as the concentration increases, the behavior of the solution transitions to non-Newtonian, displaying shear-thinning properties. This means that as shear is applied (for example, during mixing or pumping), the viscosity decreases, facilitating easy processing. This characteristic is particularly advantageous in industries like construction, where HEC-based slurries can be easily applied and spread before setting.
