Vae Powder Factory Rdp Powder for Dry Mix Mortar

VAE (Vinyl Acetate Ethylene) powder, also known as RDP (Redispersible Polymer Powder), is a dry, white or cream-colored powder that is used as an additive in dry-mix mortar. It is made by spray-drying a vinyl acetate-ethylene copolymer emulsion.

VAE powder is hygroscopic, meaning it readily absorbs moisture from the air. It is important to store VAE powder in a cool, dry place in a sealed container to prevent it from absorbing moisture and clumping.

Benefits of using VAE powder in dry-mix mortar:

  • Improved workability: VAE powder makes mortar easier to mix, apply, and smooth.
  • Increased water retention: VAE powder helps mortar retain water, which is important for proper hydration and setting.
  • Improved adhesion: VAE powder helps mortar adhere better to substrates.
  • Increased flexibility: VAE powder makes mortar more flexible, which helps to prevent cracking.
  • Improved water resistance: VAE powder helps to make mortar more water resistant.
