Construction additive Rdp (Redispersible Polymer Powder) vae
RDP (Redispersible Polymer Powder), also known as VAE (vinyl acetate-ethylene) powder, is a versatile additive used in various construction materials. It’s a white, odorless powder that readily disperses in water to form a milky emulsion, acting as a binder and adhesive.
Benefits of using RDP:
- Improved workability: RDP makes mixes more workable and cohesive, improving troweling, pumping, and spraying properties.
- Enhanced strength and flexibility: It strengthens mortars, plasters, and self-leveling compounds, increasing crack resistance and flexibility.
- Reduced water absorption: RDP improves water resistance in construction materials, leading to better durability and reduced efflorescence (salt deposits on the surface).
- Improved adhesion: It enhances the adhesion of construction materials to substrates like brick, concrete, and wood.
- Increased freeze-thaw resistance: RDP helps materials withstand freeze-thaw cycles, making them suitable for outdoor applications.
