redispersible latex powder RDP for tile adhesivesDecember 7th 2023
Redispersible Polymer Powders are essential for achieving the desired properties in cement-based and gypsum-based dry powder materials. For starters, they offer improved workability since they can reduce cracking due to their plasticizing effect on mortar. Secondly, they provide higher strength since they can improve early-age strength development and increase compressive strength after 28 days. Thirdly, they have better water retention capability since they can reduce water penetration into substrates due to their hydrophobization effect on mortar.
Moreover, these powders can also improve adhesion between layers and between mortar and substrate due to their excellent wetting properties. Finally, they have improved freeze/thaw resistance since they can reduce damage caused by repeated freeze/thaw cycles when used in exterior applications.
