RDP(Redispersible Polymer Powder)

RE-508F Flexible Redispersible Polymer Powder For Dry-Mix Mortars

Redispersible Polymer Powder (RDP) works as a crucial polymeric binder and flexibility enhancer in ready-mixed dry materials—helping improve adhesion, cohesion, and overall mechanical performance in systems such as tile adhesives, flexible mortars, and EIFS skim coats.

RE-508F is a flexible-type Ethylene-Vinyl Acetate copolymer powder designed to dramatically enhance the deformation ability and bending strength of cement- and gypsum-based mortars. With excellent water solubility and good saponification resistance, it delivers superior elongation and wear resistance without affecting thixotropy or water retention, supporting exceptional adhesion in highly recommended applications like tile adhesives (at a 1.5%–5% dosage)—an ideal choice for producing high-quality flexible mortars and patching compounds.
