Redispersible polymer powder is a free-flowing, thermoplastic, water-dispersible powder made from various synthetic polymers. It is produced by spray-drying a polymer dispersion or emulsion, resulting in individual polymer particles encapsulated in a protective shell. RDP is designed to be easily redispersed in water, forming a stable polymer dispersion.

RDP is commonly used as an additive in a wide range of construction materials, including adhesives, mortars, coatings, and self-leveling compounds.
