What is Redispersible Polymer Powder?

Redispersible polymer powder is a white, free-flowing powder. It comes from the process of drying polymer emulsions. When mixed with water, it forms a stable emulsion again. This quality is vital for many applications.

Where is RDP Used?

RDP finds its place in several construction materials. Here are some key areas:

  1. Tile Adhesives: RDP improves adhesion and flexibility.
  2. Thin-Set Mortars: It enhances workability and bonding.
  3. Repair Mortars: RDP adds resilience against cracking.
  4. Leveling Compounds: It improves flow and leveling properties.
  5. Exterior Insulation Systems: It contributes to weather resistance.

  • Flexibility: It allows for more flexibility. Your structures can handle movement without cracking.
  • Water Resistance: RDP makes materials resistant to moisture. This leads to longer-lasting results.
  • Improved Workability: It makes mixing easier. Your workers will appreciate the smoother application.

How to Use Redispersible Polymer Powder

Using RDP is straightforward, but it helps to know a few tips:

  1. Mixing: Always mix RDP with dry ingredients first. This helps achieve a uniform distribution.
  2. Water Addition: Add water gradually. This prevents clumping and ensures a smooth mix.
  3. Storage: Keep RDP in a cool, dry place. This extends its shelf life and maintains its quality.
