Brief Introduction:
Redispersible Polymer Powder (RDP) is a free-flowing white powder made by spray-drying polymer emulsions. It readily redisperses in water to form a stable emulsion and is widely used as a key additive in dry-mix mortar formulations. RDP enhances important properties such as adhesion, flexibility, water resistance, and workability. It is especially used in tile adhesives, external thermal insulation systems (ETICS/EIFS), self-leveling compounds, repair mortars, and gypsum-based plasters. By improving cohesion and durability, RDP helps improve the overall performance and longevity of construction materials.
