Redispersible Polymer Powder Rdp for Construction

Redispersible Polymer Powder (RDP), also known as redispersible latex powder, is a fine, dry powder that acts as a binder and modifier in dry-mix mortar products used in construction . It’s made by spray-drying a polymer emulsion, most commonly ethylene vinyl acetate (EVA), with a protective colloid like polyvinyl alcohol (PVA)

RDP offers several advantages over traditional cement-based mortars:

  • Improved adhesion and flexibility: RDP helps the mortar better bond to substrates and makes it more flexible, reducing the risk of cracking.
  • Increased strength: RDP can improve the compressive and flexural strength of mortars.
  • Enhanced workability: RDP makes mortars easier to mix and apply.
  • Improved water resistance: RDP helps to repel water and improve the durability of mortars in wet environments.
  • Reduced shrinkage: RDP can help to reduce shrinkage cracking in mortars.
