RDP/VAE Description:

Re-dispersible Polymer Powder (RDP/VAE)

The Re-dispersible Polymer Powder is a white powder made from VAE(vinyl acetate) emulsion and PVA. The RDP can dissolved quickly in normal water. It is good film forming agents in putties and skim coat. This film with RDP has the advantages of high weather resistance, toughness and strong adhesion on different substrates. No chalking or cracking happen in different weathers. Mortars with RDP can glue together with different substrates, reinforce mortar struture and provide excellent adhesion on cement or gypsum based dry mixed mortar substate interface.

RDP(Re-dispersible Polymer Powder)Advantage:

  1. Excellent waterproof performance.
  2. Improves the construction efficiency.
  3. After dispersing into a film, the polymer resin is distributed throughout the mortar system, and gradually plays a high bonding role over time to increase the cohesion of the mortar.
  4. Increase the elasticity of mortar and make it open to work for a long time, so that the mortar has excellent alkali resistance.
  5. Make the mortar resistance of cracking.

RDP Typical Application:

1.Tile adhesive /Tile grout.

  1. Wall putty/Skim Coat.
  2. ETIFS mortar.
  3. Self-leveling cement mortar.
  4. Flexible crack resistant mortar.
  5. ETRIS(external thermal insulating rendering systems made of mortar with mineral binder and using expanded polystyrene granule as aggregate) mortar.
  6. Blocks/Panel Jointing mortars.
  7. Polymer mortar products which has high requirement on flexibility.
