VAE redispersible polymer powder improve deformability and bonding strength on various substrates, even under critical conditions.It offers a number of benefits to the wet and dry-mortar properties of tile adhesives.When mixed with the required amount of water, the dry-mix mortar fully disperses the VAE re-dispersible polymer powder into the aqueous phase.This is the precondition for a homogeneous film formation of the polymer during the subsequent setting of the mortar. In addition to the cement matrix the polymer matrix contributes to the bonding and compressive strength of the mortar.
