RDP Vae Powder Used in Wall Putty

October 18th 2023
SLEOCHEM

RDP VAE (Redispersible Polymer Powder Vinyl Acetate Ethylene) is a type of polymer powder commonly used in construction materials like wall putty, tile adhesives, and other cement-based products. It is produced by spray-drying a mixture of vinyl acetate and ethylene monomers in an aqueous environment along with protective colloids and additives.

When RDP VAE powder is incorporated into wall putty, it serves several purposes:

  1. Improved Workability: RDP VAE powder enhances the workability of the wall putty mixture, making it easier to spread, apply, and shape on surfaces.
  2. Adhesion: It promotes better adhesion of the putty to various substrates, including concrete, masonry, and drywall surfaces.
  3. Flexibility: RDP VAE imparts flexibility to the wall putty, reducing the risk of cracking due to structural movement, temperature changes, or settling.
  4. Water Resistance: Incorporating RDP VAE can enhance the water resistance of the wall putty, making it less likely to soften or degrade when exposed to moisture.
  5. Durability: The polymer in the RDP VAE powder contributes to the overall durability and longevity of the wall putty layer.
  6. Workability Retention: RDP VAE powder helps the putty maintain its workability over an extended period, allowing for better finishing and smoother application.
  7. Improved Rheology: Rheology refers to the flow and deformation behavior of materials. RDP VAE powder can improve the rheological properties of the putty, leading to better consistency and handling.
  8. Reduced Dust Generation: The powder form of the polymer aids in reducing dust generation during mixing and application.
