Redispersible Polymer Powder
RDP (Redispersible Polymer Powder)
Michem Redispersible Polymer Powder (RDP) is a free-flowing white powder obtained by spray-drying polymer emulsions, mainly based on vinyl acetate-ethylene (VAE). When mixed with water, RDP quickly redisperse into a stable emulsion, retaining the original properties of the polymer. It is widely used in dry-mix mortar formulations, specifically suited for tile adhesives, renders, plasters and skim coats to enhance adhesion, flexibility, water resistance, and long-term durability.
