Re-Dispersible Polymer Powder(RDP)
Genreal:
Redispersible polymer powder, also known as VAE or RDP , it is a powder binder made from a special emulsion (high molecular polymer) spray-dried. The VAE/RDP powder can be quickly dispersed to form an emulsion after solving into water, and has the same properties as the initial emulsion, that is, a film can be formed after the water evaporates. This film has high flexibility, high weather resistance and good adhesion to various material, is an essential functional additive for dry-mix mortar.

Advantages and Features
Features of Redispersible Emulsion(vae) powder:
● High adhesion and bonding strength
● Water resistance
● Good workability and rheology
● Improved flexibility and durability
● Increased impact and abrasion resistance
● Good freeze-thaw stability
Dispersible polymer powder(VAE/RDP) characteristics
• High flexibility, good film formation
• High water resistance for increased open time
• High hydrophobicity, ability to bridge cracks
• Viscous texture and high workability
• Excellent cohesion, on difficult substrates, with excellent bond strength after prolonged exposure to water
• High binding capacity, redispersible polymer powders are especially used in construction work to create durable adhesives and coatings for tiles, seals, conduits and pipes.
Applications:
Redispersible Emulsion powder is mainly used ininterior and exterior wall putty powder, tile adhesive, tile jointing agent, dry powder interface agent, interior and exterior wall insulation mortar, self-leveling mortar, repair mortar, decorative mortar, waterproof mortar, etc.
● Mortar and grout: RDP powder is used in cement-based mortars and grouts to improve their adhesion, workability, and durability.
● Tile adhesives: VAE powder is added to tile adhesives to increase their bonding strength, water resistance, and flexibility.
● Exterior insulation and finishing systems (EIFS): RDP powder is used in EIFS to improve the system's flexibility, adhesion, and resistance to cracking.
● Self-leveling compounds: VAE powder is added to self-leveling compounds to enhance their workability and durability.
● Gypsum-based products: RDP powder is used in gypsum-based products to improve their water resistance, adhesion, and strength.
